Introduction, Conservation, fluid statics;
Fluid flow:Newton's law of viscosity, Non-newtonian fluids, continuity equation, Navier-Stokes equations, Laminar flow, Turbulence and experimental correlations, concept of friction factor, flow through porous media, fluidized bed.
Heat Transfer: Heat conduction - Fourier's law - steady state conduction - plane wall - cylindrical wall - application in estimating heat losses from furnaces - unsteady state conduction - Heisler's charts - Thermally thick and thin bodies - application in heat treatement - solidification. Convection - Introduction of boundary layer concept - heat transfer coefficient - correlation for external flow and internal flow - problems from pipe flow - cooling systems in reactors - continuous casting cooling system - free convection correlations - heat losses from hot surfaces . Radiation - definitions - black body - grey body - view factor between surfaces - problems from furnaces, reactors in used in materials processing - radiation shields Case studies invovling multimode heat transfer in materials processing.
Fick's Law of diffusion - advection due to diffusion - case of evaporation of liquid through a column, Analog between mass and heat transfer - mass transfer coefficient - application in gas-solid reactions such as oxidation, reduction etc.
