Introduction to heat transfer
processes: thermal conductivity of solids, Liquids and gases; effect of
temperature. Conduction: Fourier's law; general 3
dimensionals conduction equation; different kinds of boundary conditions; nature
of differential equations; one dimensional heat conduction with and without heat
generation; electrical analogy; heat conduction through composite walls;
critical thickness of insulation; heat transfer from finned surfaces; fin
effeciency and effectiveness Convection: Review of Navier - Stokes and energy
equations, hydrodynamic and thermal boundary layers; laminas boundary layer
equations; forced convections appropriate non dimensional members; flow over
flat plate; similarity solution; Von Karman's method; effect of Prandtl number;
laminar flow through circular pipe; constant heat flux and constant wall
temperature conditions, empirical relations. Natural
Convection: Dimensional analysis, Grashoff number, boundary layers in
external flows (flow over a plate only), boundary layer equations and their
solutions, heat transfer correlations Heat Transfer with change of
phase: Nature of vaporization phenomena; different regimes of boiling
heat transfer; correlations for saturated liquid vaporization; condensation on
flat plates; correlations of experimental results, drop wise
condensation Heat Exchanger: Different types of heat
exchanger, arithmetic and logarithmatic mean temperature differences, heat
transfer coefficient for parallel counter and cross flow type heat exchanger;
effectiveness of heat exchanger, N.T.U. method, fouling
factor Thermal Radiation: Plank distribution law. Krichoff's
law: radiation: radiation properties, diffuse radiations; Lambert's law.
Radiation intensity, heat exchange between two block bodies heat exchange
between gray bodies. Shape Factor: electrical analogy; retardiating surfaces
heat transfer in presence of retradiating surfaces. Introduction to
Mass Transfer: Mass and mole concentrations. molecular diffusion, eddy,
diffusion from an evaporation fluid surface. Mass transfer in laminar and
turbulent convections. Raynold's analogy. Combined heat and mass transfer the
wet and dry build thermometer.
