IIT BHU Varanasi Syllabus Ceramic Heat and Mass Transfer

 

 

Heat and Mass Transfer

Heat Transfer: Steady state conduction with and without heat source in one dimension for single, composite plane,

cylindrical and spherical walls. Thermal insulation and selection of insulating materials. Unsteady heat conduction;

use of charts.

Concept of film resistance and thermal boundary layer, heat transfer coefficient solution of laminar forced

convection of flat plate, working formulae and dimensionless correlation for forced convection inside tubes, annular

spaces and normal to single tube banks. Elementary  idea of Reynolds, Prandtl and colburn analogies. Current,

counter-current and cross-flow heat exchangers. Code in heat exchangers design.

Basic laws of radiative heat transfer. View factors and derivation for simple systems and also their determination

using charts. Radiative heat transfer in glass melting and calculations of radiative  heat transfer in furnaces.

Mass Transfer: Mass transfer by molecular diffusion. Mass Transfer in system of fluids, granular solids and

fluidized beds. Mass transfer coefficient and their correlation. Height of Transfer Unit (H.T.U.) and  Number of

Transfer Units (N.T.U.) calculations. Mass Transfer applied to absorption. Continuous contact equipment for gasabsorption. Psychometry; Humidity, wet and dry bulb temperatures. Adiabatic humidification and dehumidification.

Pumping of fluids calculation/design.

Drying: Internal flow of moisture within the solids, surface evaporation, drying shrinkage, estimation of drying

rates and achievement of maximum drying rate. Detail study of the various driers used in ceramic industries: Tray

driers, tunnel driers, drum driers, vacuum driers and spray driers.
