Microscopic Theory of Transport, Fall 2003

Abstract:: Discusses basic physical mechanisms of particle and radiation transport due to microscopic collisions. Simple explanation of transport coefficients (e.g., diffusivity, viscosity, heat conductivity, electrical conductivity) and various nuclear cross sections. Derivation of the microscopic kinetic equation describing transport; the Boltzmann equation. Derivation of practical engineering fluid models (e.g., classical thermodynamics, the Navier Stokes equations, the neutron transport equations) from the kinetic model. Subject material elucidates the common roots of these widely different models. Transport is among the most fundamental and widely studied phenomena in science and engineering. This subject will lay out the essential concepts and current understanding, with emphasis on the molecular view, that cut across all disciplinary boundaries. (Suitable for all students in research.) Broad perspectives of transport phenomena; From theory and models to computations and simulations; Micro/macro coupling; Current research insights

Transport Processes in the Environment, Fall 2004

Abstract:: Introduction to momentum and scalar transport in environmental flows, with emphasis given to river and lake systems. Derivation and solutions to the differential form of mass conservation equations. Topics include: molecular and turbulent diffusion, boundary layers, dissolution, phase partitioning, bed-water exchange, air-water exchange, settling and coagulation, buoyancy-driven flows, and stratification in lakes.
