pressure drops in packed beds. Effect of particle shape. Concept of wall
support and effects of compressible media. Concept of critical velocity.
Heat transfer
Introduction: Mechanisms and applications of
heat transfer-mode of heat transfer-conduction, convection and radiation.
Steady state heat transfer fundamentals:
Resistances to heat transfer. Heat transfer in heat exchangers and fermenter
coils, jacketed vessels. Principles of heat transfer underlying condensation
and evaporation. Unsteady state heat transfer fundamentals.
Mass Transfer:
Diffusion and Mass transfer coefficient:
Diffusivity and mechanism of mass transfer - derivation of the equations of
mass transport by diffusion-stationary and unsteady mass transport by
diffusion-convective mass transport-mass transfer coefficient, macroscopic
balances for mass transport.
Application of Heat and Mass transfer:
Absorption, Distillation principles, phase diagrams and equilibrium curves,
non-ideal systems, continuous distillation, McCabe - Thiele method, column
operation. Drying principles and operation.
