MY1008 TRANSPORT PHENOMENA IN METALLURGY
OBJECTIVE
The course is primarily concerned with transport phenomena momentum, heat and mass and its applications – primarily to metallurgical systems.
1. MOMENTUM TRANSFER
Units, Properties of fluids, various types of fluid flow, Reynolds experiments, concept of velocity boundary layer, friction in pipes and channels, flow past submerged bodies, supersonic nozzles, flow through packed beds and fluidised beds.
2. CONDUCTION AND CONVECTION
Fourier’s law, conduction in solids, liquids and gases, steady state and unsteady state conduction in solids, Natural and forced convection, concept of heat transfer co-efficient and thermal boundary layer.
3. RADIATION AND SOLIDIFICATION HEAT TRANSFER
Radiation heat transfer - view factors, gas radiation, radiant heat transfer between surfaces, Gurnie - Lurie, Haisler, Hottel charts. Heat transfer with change of phase, solidification heat transfer and application, heat transfer in packed beds and fluidised beds.
4. MASS TRANSFER
Diffusivity and steady state diffusion, unsteady state mass transfer, concept of mass transfer co-efficient, concentration boundary layer, interphase, mass transfer - theories, simultaneous mass and heat transfer
5. DIMENSIONAL ANALYSIS AND SIMILARITY CRITERIA
Introduction to staged operations, dimensional analysis, similarity criteria and pilot plant studies, similarities of momentum, mass and energy transfer.
