Course outline Review of conduction, resistance concept, extended - PowerPoint PPT Presentation

Course outline • Review of conduction, resistance concept, extended surfaces, lumped capacitance • Radiation • Introduction to Convection, boundary layer theory, natural and forced convection, correlations • Heat exchangers • Interphase mass transfer, mass transfer coefficient, theories for interphase mass transfer, overall mass transfer coefficient, correlations • mass transfer with chemical reaction • simultaneous heat and mass transfer • analogy between momentum, heat and mass transfer

Mathematics is a language of science Experimentation is also a language of science In this course … • Science behind (heat and mass) transport processes • Methods to model and analyze • Mathematics as a tool

Applications – in several length and time scales • Consumer items Uptake of detergents, Leaching of dirt, Softeners • Food Lassi making, Uptake rate, Juice making, … • Infrastructure Car (radiators, mufflers, ….), air conditioner, drug manufacturing • Diseases Drug uptake, Cellular transport, Fever, Dialysis … • Environment Global warming, aerosol transport, … • Lot more to come … India needs engineers to come up good, low cost processes
