CHEM E 531
Continuation of CHEM E 530. Flows of fluid-particle systems; convective heat transfer, natural convection. Prerequisite: CHEM E 530.
Many (if not most) transport phenomena of interest involve coupling of two or more transport processes. Classic examples from chemical engineering include coupling of heat and/or mass transfer to fluid flow, or multicomponent diffusion in fluid mixtures. But transport coupling also plays a crucial role in condensed and/or ionic media (crystalline solids, polymers, electrolytes), where many properties arise from interactions of heat, charge, and mass transport. This course will investigate the origins of these coupling mechanisms, their consequences, and means for modeling them in practical applications. Topics of interest include:
Forced and natural convection in heat and mass transfer Nonequilibrium thermodynamic foundations of transport; Onsager reciprocal relations, microscopic reversibility. Dilute, moderately dilute, and concentrated solution theory; role and definition of activity and potential in ionic and electron transport Speciation in crystalline solids: relation to defect and electronic structure Defect diffusion and electron/hole transport in semiconductors Soret and Hall effects, thermoelectric effect Electro-osmotic flow, electrophoresis, electrocapillary effects Molecular and ion transport in polymers Surface diffusion
Student learning goals
General method of instruction
The format of the course will be partially lecture, partially seminar: two lectures per week with a problem set, and one paper reading per week, to be discussed in-class. An individual project involving some aspect of the students own research or interest will be due at the end of the quarter.
Advanced engineering mathematics, Chem E 530 (or equivalent), or by permission of the instructor
