TH:11 - 12:15
This course introduces the topic of Transport Phenomena, which involves the development of mathematical models and physical understanding of the transfer of momentum, energy and mass. In this first course, momentum transfer is studied thus involving the motion and deformation of fluids (a.k.a. Fluid Dynamics). Because chemical engineers often need a detailed understanding of flow within small scale devices (catalyst pellets, living animal tissue, high-density processor chip manufacture), considerable emphasis is placed on the differential equations that describe fluid flow. The balance equations for large-scale equipment (macroscopic equations) are also considered. Despite the (necessary) emphasis on developing mathematical models to describe flow phenomena, a major goal for students taking this class is to develop sound physical understanding of these flows so that they can correctly apply models in new situations that they may encounter.

This shows how to use a similarity variable to reduce the boundary layer equations for energy and momentum, for a natural convection flow caused by a heated surface, to a set of ODE's. A shooting method is employed to solve them. It uses the notation of and is based on F. P. Incropera and D. P. DeWitt, Fundamentals of Heat and Mass Transfer.

This notebook looks at chemical reactions in a stirred tank reactor for single phase, liquid-solid and gas-liquid solid systems. For gas-liquid packed bed (a. k. a. "trickle - bed") reactors, flow disturbances cause fluctuations in the mass transfer rate. This notebook shows how these fluctuations can influence the reaction selectivity. The fluctuation (pulsing) frequency is seen to be a key variable. It uses the notation of and is based on R., M. J. McCready and A. Varma "Influence of mass transfer coefficient fluctuation frequency on performance of three-phase packed bed reactors, Chemical Engineering Science.,
