Course No. Course Title Instructor In-charge : CHE F414 : Transport Phenomena : PRATIK N SHETH 1. Course Description Analogy for momentum, heat and mass transport; shell balance approach for analysis of individual and simultaneous momentum, heat and mass transport; hydrodynamic and thermal boundary layers; velocity, temperature and concentration distributions in turbulent flow; interphase transport for isothermal and non-isothermal systems. 2. Scope and Objectives Develop the understanding of the three transport mechanisms i.e. momentum, heat and mass transfer Analyze the analogy in three transport mechanisms in terms of governingg laws Represent the process behavior mathematically by applying the transport phenomena fundamentals o Apply the shell balance (mass, momentum and energy) or o Develop the system of partial/ordinary differential equations o Find the required boundary based on the understanding of the physics of the system o Solve governing equations to find velocity/concentration/temperature/pressure profile using methods Develop the equation of continuity and equation of change of mass, momentum and energy Apply the equation of change to a real physical system and deduce the governing equation by eliminating the few terms (representing phenomena not occurring in the process) Use the CFD software and develop the flow field, temperature profile in simple systems 3.
