Direct Energy Conversion discusses both the physics behind energy conversion processes and a wide variety of energy conversion devices. A direct energy conversion process converts one form of energy to another through a single process. The first half of this book surveys multiple devices that convert to or from electricity including piezoelectric devices, antennas, solar cells, light emitting diodes, lasers, thermoelectric devices, and batteries. In these chapters, physical effects are discussed, terminology used by engineers in the discipline is introduced, and insights into material selection is studied. The second part of this book puts concepts of energy conversion in a more abstract framework. These chapters introduce the idea of calculus of variations and illuminate relationships between energy conversion processes.

This peer-reviewed book is used for a junior level electrical engineering class at Trine University. However, it is intended not just for electrical engineers. Direct energy conversion is a fascinating topic because it does not fit neatly into a single discipline. This book also should be of interest to physicists, chemists, mechanical engineers, and other researchers interestedin an introduction to the energy conversion devices studied by scientists and engineers in other disciplines

Flying more missions than any other shuttle, Discovery carried out every type of mission NASA had to offer, spending a total of 365 days in space, and checking off many firsts in spaceflight.

Over 30 years ago, Discovery ascended into space for the first time, after three thwarted launch attempts. Originally scheduled to lift off in June 1984, Discovery finally launched on August 30.

This lab exercise utilizes a small (and relatively easy to make) wind tunnel with a fog tracer that helps students visualize the flow dynamics around obstacles. In this exercise the use of cylinders perpendicular to the flow allows for estimations of drag coefficients and visualization of different Reynolds number flow patterns. Wind tunnel instructions are included.

In dredging, production estimating is carried out mainly with analytical physical models of the different dredging processes.
Slurry transport of settling slurries and cutting processes in sand, clay and rock are already covered in two other books by the author.
Other processes like hopper sedimentation and erosion, water jet fluidization, cutter head spillage, pump/pipeline dynamics and clamshell dredging are covered in this Special Topics Edition.
New topics may be added in the near future.

The purpose of this course is to convey knowledge of the various physical processes associated with slurry handling and transport during dredging. This knowledge is needed for the design of dredging equipment and for planning efficient equipment operations. The various processes are discussed and theories and simulation models that describe the processes are presented and compared during the course. The course can be broken down into four elements: 1. Pumps and engines a. Pump characteristics and cavitation b. Influence of particles on pump characteristics. 2. Hydraulic transport in pipelines a. Two-phase (solid-liquid) flow through pipelines b. Newtonian slurries c. Non Newtonian slurries d. Inclined and long pipelines. 3. Pump and pipeline systems a. Operation point and areas b. Production factors. 4. Case studies

L’énergie solaire au Sénégal : un droit, des droits, une histoire

Long Description:
L’énergie solaire est une promesse de développement et de prospérité pour l’Afrique. Elle a été annoncée et expérimentée sur le continent dans un esprit de science ouverte et de « communs » technologiques et énergétiques il y a déjà près de soixante ans. Séchoirs et chauffe-eaux, pompes solaires et centrales électriques thermodynamiques : des pionniers ont développé et installé, dès la fin des années 1950, des techniques et des matériels en Afrique de l’Ouest et en particulier au Sénégal.

Le présent ouvrage, issu de deux journées d’études organisées à Dakar en mai 2016, rend compte pour la première fois, de manière particulièrement symbolique, de cette histoire et du futur de l’énergie solaire en Afrique. Il rassemble, dans une première partie, des témoignages d’acteurs et une mise en perspective sociohistorique large des politiques de l’énergie solaire en Afrique de l’Ouest sur un demi-siècle. Ce regard est complété par la réédition d’un texte de référence du professeur Abdou Moumouni Dioffo, pionnier nigérien de l’énergie solaire dès 1964.

Dans une seconde partie, cet ouvrage interroge également les prolongements actuels de l’énergie solaire en France et au Sénégal, en particulier son encadrement juridique et réglementaire. L’énergie solaire peut-elle ou doit-elle être considérée comme un « commun » ou un droit humain fondamental? Quels sont aujourd’hui les droits associés à l’énergie solaire au Sénégal? Quels enseignements tirer d’une comparaison avec le corpus juridique en la matière tel qu’il existe en France?

Associant juristes français et sénégalais, et spécialistes de la sociologie et des politiques de l’énergie, cet ouvrage se veut au final une invitation et un outil pour poursuivre les recherches sur l’histoire et le droit de l’énergie solaire en Afrique.

These dynamics course notes were authored by Dr. Elizabeth Croft (currently at Monash University (elizabeth.croft@monash.edu) in 2004, and converted for open licensing (including figure creation) in 2019 by Dr. Agnes d'Entremont (adentremont@mech.ubc.ca) from the Department of Mechanical Engineering at the University of British Columbia, Vancouver, Canada (https://mech.ubc.ca).

The notes (are designed to be used for a second-year dynamics course in Mechanical Engineering, and cover planar rigid-body dynamics and an introduction to one degree-of-freedom vibrations. The order of topics has vibrations earlier in the series than typical, due to their use in an integrated course. This order matches the course timing of related ordinary differential equation solutions in the integrated mathematics and electric circuits courses.

These notes are intended to be skeleton notes, with substantial portions (diagrams, derivations, solutions) written in by students along with their instructor. Completed notes are included. PDF notes plus original LaTeX code and editable images (Powerpoint) are available at the link.

In this course you will start by identifying the different steps a HVAC (Heating, Ventilation and Air Conditioning) engineers need to follow to come to a proper design while collaborating with the architect.

You will then learn how to distribute heat and cold using air and water systems, what temperature levels to use in both and how that relates to the type of energy supply and to the thermal quality of the building construction. You will further deepen your knowledge on air handling units and how to humidify and dehumidify air when needed and what that does mean for the energy consumption. As ventilation systems are often responsible for local thermal discomfort, you will also discover how different distribution systems lead to different comfort experiences and different indoor air qualities and you will know which simple control techniques can be applied.

Finally you will study a modern complex system consisting of an aquifer thermal storage, heat pump, boiler, solar collector, PV-cells, air handling unit, water and air distribution systems. This will allow you to develop skills to catch the complexity of such HVAC systems and to understand the basic rules of how to control them to get the best out of them and how to use data from the Building Energy Management System to help you in this task.

Current is the flow of charge. We measure current by counting the amount of charge passing through a boundary in one second. Created by Willy McAllister.

Electrochemical engineering deals with electrochemical devices like electrolysers, fuel cells, and batteries. While several excellent books exist in this long-standing and still growing field, their focus is usually on chemistry or phenomenology. In this textbook, we focus on mathematical modelling of the physical phenomena involved. Instead of resorting to numerical modelling, the aim is to derive simplified analytical models that maximise understanding.

Porous electrodes, ion mass transport, and multiphase flow are central themes in this book. Examples include modelling the water saturation in a fuel cell diffusion layer, the gas fraction and current distribution in an alkaline water electrolyser, the potential distribution in a binary electrolyte inside porous battery electrode, and the concentration distribution in the flow channel of a redox flow battery. This makes for a diverse, challenging, and stimulating journey, for both students and researchers.

This course discusses applications of electromagnetic and equivalent quantum mechanical principles to classical and modern devices. It covers energy conversion and power flow in both macroscopic and quantum-scale electrical and electromechanical systems, including electric motors and generators, electric circuit elements, quantum tunneling structures and instruments. It studies photons as waves and particles and their interaction with matter in optoelectronic devices, including solar cells, displays, and lasers.
The instructors would like to thank Scott Bradley, David Friend, Ta-Ming Shih, and Yasuhiro Shirasaki for helping to develop the course, and Kyle Hounsell, Ethan Koether, and Dmitri Megretski for their work preparing the lecture notes for OCW publication.

This text is an introductory treatment on the junior level for a two-semester electrical engineering course starting from the Coulomb-Lorentz force law on a point charge. The theory is extended by the continuous superposition of solutions from previously developed simpler problems leading to the general integral and differential field laws. Often the same problem is solved by different methods so that the advantages and limitations of each approach becomes clear. Sample problems and their solutions are presented for each new concept with great emphasis placed on classical models of physical phenomena such as polarization, conduction, and magnetization. A large variety of related problems that reinforce the text material are included at the end of each chapter for exercise and homework.

Published in 1989 by Prentice-Hall, this book is a useful resource for educators and self-learners alike. The text is aimed at those who have seen Maxwell's equations in integral and differential form and who have been exposed to some integral theorems and differential operators. A hypertext version of this textbook can be found here. An accompanying set of video demonstrations is available below.
These video demonstrations convey electromagnetism concepts. The demonstrations are related to topics covered in the textbook. They were prepared by Markus Zahn, James R. Melcher, and Manuel L. Silva and were produced by the Department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology.
The purpose of these demonstrations is to make mathematical analysis of electromagnetism take on physical meaning. Based on relatively simple configurations and arrangements of equipment, they make a direct connection between what has been analytically derived and what is observed. They permit the student to observe physically what has been described symbolically. Often presented with a plot of theoretical predictions that are compared to measured data, these demonstrations give the opportunity to test the range of validity of the theory and present a quantitative approach to dealing with the physical world.
The short form of these videos contains the demonstrations only. The long form also presents theory, diagrams, and calculations in support of the demonstrations.
These videos are used in the courses 6.013/ESD.013J and 6.641.

Elementary Differential Equations with Boundary Value Problems is written for students in science, engineering, and mathematics who have completed calculus through partial differentiation. If your syllabus includes Chapter 10 (Linear Systems of Differential Equations), your students should have some preparation in linear algebra. In writing this book I have been guided by the these principles: An elementary text should be written so the student can read it with comprehension without too much pain. I have tried to put myself in the student's place, and have chosen to err on the side of too much detail rather than not enough. An elementary text can't be better than its exercises. This text includes 2041 numbered exercises, many with several parts. They range in difficulty from routine to very challenging. An elementary text should be written in an informal but mathematically accurate way, illustrated by appropriate graphics. I have tried to formulate mathematical concepts succinctly in language that students can understand. I have minimized the number of explicitly stated theorems and defonitions, preferring to deal with concepts in a more conversational way, copiously illustrated by 299 completely worked out examples. Where appropriate, concepts and results are depicted in 188 figures

This is an advanced course on modeling, design, integration and best practices for use of machine elements such as bearings, springs, gears, cams and mechanisms. Modeling and analysis of these elements is based upon extensive application of physics, mathematics and core mechanical engineering principles (solid mechanics, fluid mechanics, manufacturing, estimation, computer simulation, etc.). These principles are reinforced via (1) hands-on laboratory experiences wherein students conduct experiments and disassemble machines and (2) a substantial design project wherein students model, design, fabricate and characterize a mechanical system that is relevant to a real world application. Students master the materials via problems sets that are directly related to, and coordinated with, the deliverables of their project. Student assessment is based upon mastery of the course materials and the student's ability to synthesize, model and fabricate a mechanical device subject to engineering constraints (e.g. cost and time/schedule).

Building design strongly influences the quantity of heating, cooling and electricity needed during building operation. Therefore, a correct thermal design is essential to achieve low energy and low carbon buildings, with good indoor air quality.

This course will enable you to understand the basic principles of the energy chain: demand, supply and distribution; and how they relate to design principles for sustainable and energy-efficient buildings.

Second, you will discover what type of heat losses and gains take place in buildings’ operations. You will learn how to estimate these flows using simple meteorological data and construction properties. You will acquire knowledge on how to estimate heat transfer through construction, ventilation, solar radiation or caused by internal sources or heat storage in the construction.

Third, you will learn to make estimates of buildings’ energy needs on an hourly basis by using simple static energy balances: how much energy comes in and out and which air temperature is needed? When is there heating or cooling? How much electricity is needed?

Fourth, you will discover how to extend your estimates to yearly energy demand, which is essential to make sure that a building is energy efficient and to estimate energy savings and energy costs. You will then also be able to determine the size of the needed heating and cooling equipment (which determines the costs of equipment).

Finally, you will learn how to optimize building design and will be able to find out the optimal window size or the optimum insulation thickness for your building. You will know why putting windows on the south façade is not always energy-efficient. You will understand the thermal interactions between building components and be able to make informed decisions on how to increase the energy efficiency of new and existing buildings.

This course is part of the PCP Buildings as Sustainable Energy Systems. In the other courses in this program you can learn how to choose low carbon energy supply, how to create a comfortable indoor environment, and how to control and optimize HVAC systems.

This course explores the theoretical and empirical perspectives on individual and industrial demand for energy, energy supply, energy markets, and public policies affecting energy markets. It discusses aspects of the oil, natural gas, electricity, and nuclear power sectors and examines energy tax, price regulation, deregulation, energy efficiency and policies for controlling emission.

In this course, you will discover the supply side of buildings’ energy chain.

The first step is to consider how to convert natural resources into the energy needed by buildings: what are the options to create heat, cold and electricity? You will learn about efficiency and use this concept to estimate building’s primary energy use and carbon emissions. This concept is widely used in many national and international policies and building regulations, and is essential to counteract climate change.

You will study the performances of single heating systems like electrical heating, gas, or renewables like biomass, solar boilers and geothermal heat, followed by single cooling systems like evaporative cooling and environmental cold.

We will also examine the systems that concurrently produce heat and cold. Do you know for instance that a heat pump and a cooling machine are identical devices? You will learn about the basic working principles of heat pumps and how to make sure they achieve high performance levels. After this course you will know how an Aquifer Thermal Storage makes smart use of the ground to deliver cold in summer and heat in winter.

Diverse electricity generation methods using turbines (wind, hydro), photovoltaics or hydrogen fuel cells will also be examined. You will learn how cogeneration of heat and power works and why this is important for the rational use of energy resources. You will also know why heat pumps are often combined with boilers or to which extent it is worth to invest in batteries for your solar panels.

By the end of the course you will be able to decide on how to combine energy conversion systems at building level in order to match buildings’ energy demand while keeping costs acceptable, using a minimum of natural resources and producing a minimum of carbon emissions.

This course is part of the program Buildings as Sustainable Energy Systems. In the other courses in this program you can learn how to design buildings with low energy demand, how to create a comfortable indoor environment, and how to control and optimize HVAC systems.

Products and equipment all around us are made of materials: look around you and you will see phones, computers, cars, and buildings. We face challenges in securing the supply of materials and the impact this has on the planet. Innovative product design can help us find solutions to these challenges. This course will explore new ways of designing products.

The design of products is an important aspect of a circular economy. The circular economy approach addresses material supply challenges by keeping materials in use much longer and eventually returning materials for new use. The principle is that waste must be minimized. Products will be designed to last longer. They will be easier to Reuse, Repair, and Remanufacture. The product will eventually be broken down and Recycled. This is Design for R and is the focus of this course.

Experts from leading European universities and research organizations will explain the latest strategies in product design. Current design approaches lead to waste, loss of value and loss of resources. You will learn about the innovative ways in which companies are creating value, whilst securing their supply chains, by integrating Design for R.

This course is suitable for all learners who have an interest in product design, innovative engineering, new business activity, entrepreneurship, sustainability, circular economy and everyone who thinks that the current way we do things today needs a radical rethink.

A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.
