Objectives
An introduction to Conduction, Convection and Radiation.  The material covered provides basic knowledge in Heat Transfer both to the designer of systems and the Field Engineer.
Syllabus
Conduction: Fourier’s law of heat conduction, one dimensional steady state conduction through composite walls, plain, circular and spherical boundaries, R values, Critical thickness of insulation, Thermal contact resistance, extended surfaces (fins), Lumped heat capacity system, Conduction with internal heat generation, non steady conduction.
Principles of convection: Laminar boundary layer on a flat plate, Energy equation for the Boundary layer, Thermal boundary layer, Relation between fluid friction and heat transfer, Turbulent boundary heat transfer, Turbulent boundary layer thickness, Heat transfer for laminar and turbulent flow in pipes.  Free convection for vertical and horizontal surfaces.  Principles of dynamic similarity and dimensional analysis.
Radiation: Law of black body radiation; Kirchoff’s law; Grey body radiation; Radiation between black and grey surfaces.
Heat Exchangers.
