CHE 302: Heat and Mass Transfer Operations (4)
Learning Objectives:
Heat transfer operation will give the basic ideas of heat flow via three modes, viz. conduction, convection and radiation. The principle mechanism of these three modes of heat flow and their applications in industrial problems will be covered. While, Mass Transfer operation will offer the fundamental concepts of mass transfer through diffusive and convective mass transfer, interphase mass transfer and application of these concepts to real engineering problems using distillation and absorption.
Course Contents:
Part I (Heat Transfer Operations): Basic modes of heat transfer, Conduction: principles and basic equations of 1D, 2D and 3D conduction, Fourier's law, steady state heat transfer through composite slabs, composite cylinders and sphere; Critical thickness of insulation, Fin effectiveness and efficiency, Lumped parameter approach and significance of time constant. Convection: natural and forced convection, hydrodynamic and thermal boundary layers, Individual & overall heat transfer coefficient, log-mean temperature difference (LMTD), Empirical equations for free and forced convection, Types of heat exchangers and related problem in industries, LMTD method, effectiveness-NTU method; Radiation: black body and gray body radiation, Laws of black body radiation, Evaporation: basic concepts of vaporization, single & multiple effect evaporators.
