Detailed Syllabus:

Introduction & Heat transfer by conduction:

Nature of heat flow, Heat transfer by conduction in Solids Fourier's law ,thermal conductivity, steady state conduction in plane wall & composite walls, compound resistances in series. heat flow through a cylinder, conduction in spheres, thermal contact resistance, plane wall: variable conductivity Unsteady state heat conduction Equation for one-dimensional conduction, Semi-infinite solid, finite solid

Heat Transfer to Fluids without Phase change: Regimes of heat transfer in fluids, thermal boundary layer, heat transfer by forced convection in laminar flow, Heat transfer by forced convection in turbulent flow, the transfer of heat by turbulent eddies and analogy between transfer of momentum and heat.

Natural convection -Natural convection to air from vertical shapes and horizontal planes, effect of natural convection in laminar flow heat transfer, Free convection in enclosed spaces, mixed free & forced convection. Heat transfer to fluids with phase change -Heat transfer from condensing vapors, heat transfer to boiling liquids.

Heat exchange equipment: General design of heat exchange equipment, heat exchangers, condensers, Boilers and Calendrias, extended surface equipment, heat transfer in agitated vessels, scraped surface heat exchangers, heat transfer in packed beds, heat exchanger effectiveness (NTU method). Evaporators - Evaporators, performance of tubular evaporators, capacity and economy, multiple effect evaporators, vapour recompression. Radiation -Properties and definitions, black body radiation, real surfaces and the gray body.

Absorption of radiation by opaque solids, radiation between surfaces, radiation shielding, radiation to semi transparent materials.
