HEAT TRANSFER IN BIOPROCESSES

UNIT-I:BASICS OF HEAT TRANSFER
Various modes of heat transfers, conduction, convection, and radiation. Mechanism of heat transfer by conduction, conductive heat transfer through a series of resistances.

UNIT-II:CONDUCTIVE HEAT TRANSFER:
Steady state and unsteady state heat transfer by conduction. Heat transfer through slab and cylinder. Concept of log mean radius for transfer through pipes. Extended surface heat transfer through fins etc.

UNIT-III
Convection–Dimensional analysis, Forced convection in pipe and other geometries

UNIT-IV
Natural convection - various correlation for evaluating heat transfer coefficients.

UNIT-V
Boiling and condensations. Mechanism of boiling: Film and nucleate boiling.

UNIT-VI:HEAT TRANSFER EQUIPMENTS
Double pipe heat exchangers, Shell and tube heat exchangers, pinfin heat exchangers-Overall transfer coefficient. Overview of various types of heat exchangers and concept of LMTD.

UNIT- VII
Single and Multiple effect evaporators and problems on evaporators. Steam economy, Steam capacity, evaporators performance with various feedings viz, forward, backward and parallel.

UNIT-VIII
Analogy between heat, mass and momentum transfer. Applications of heat transfer in bioprocessing-batch sterilization and design of continuous sterilizer.

* Relevant basic numerical problems should be dealt in the units.
