CAE358 Heat Transfer Syllabus:
CAE358 Heat Transfer Syllabus – Anna University Regulation 2021
COURSE OBJECTIVE:
• To impart knowledge on various modes of heat transfer and methods of solving problems. Also to give exposure to numerical methods employed to solve heat transfer problems.
UNIT I CONDUCTION
Governing equation in cartesian, cylindrical and spherical coordinates. 1-D steady state heat conduction with and without heat generation. composite wall- electrical analogy – critical thickness of insulation – heat transfer from extended surface – effect of temperature on conductivity- 1-D transient analysis
UNIT II CONVECTION
Review of basic equations of fluid flow – dimensional analysis- forced convection – laminar flow over flat plate and flow through pipes-flow across tube banks. turbulent flow over flat plate and flow through pipes – free convection – heat transfer from vertical plate using integral method – empirical relations – types of heat exchangers – overall heat transfer coefficient – LMTD and NTU methods of analysis.
UNIT III RADIATION
Basic definitions – concept of black body – laws of black body radiation-radiation between black surfaces – radiation heat exchange between grey surfaces – radiation shielding – shape factor electrical network analogy in thermal radiation systems.
UNIT IV NUMERICAL METHODS IN HEAT TRANSFER
1-D and 2-D steady and unsteady state heat conduction – composite walls-heat generation-variable thermal conductivity- extended surfaces analysis using finite difference method- Convective heat transfer- Stream function – vorticity method- creeping flow analysis-convection-diffusion 1-D, 2-D analysis using finite difference approximation. Numerical methods applicable to radiation heat transfer.
