This course provides a comprehensive introduction to heat transfer fundamentals and their applications. The course introduces students to the analysis of steady-state and transient one- and multi-dimensional heat conduction. The course considers the analysis of heat transfer by convection using empirical and boundary layer approximations. Radiation heat transfer is considered with applications to multi-body radiation.
1. Understand a thermal system, develop the schematic diagram for the system, and apply energy balance and heat transfer models to develop governing equations.2. Set up and solve for heat transfer rates as a function of geometry and materials in 1-D conduction using various tools: i. Material Properties ii. Fourier’s Law iii. Circuit Analogy3. Estimate heat transfer from Extended Surfaces, Radial Geometry, and involving Energy Generation.4. Construct a transient heat transfer analysis, testing for the lumped capacitance approximation and understanding the assumptions.5. Understand the approach for setting up numerical analysis of heat transfer using EES to solve simultaneous sets of equations and carry out parametric investigations.6. Understand a thermal system with convection heat transfer, construct a schematic diagram for the system, characterize the geometry and flow conditions, and apply the appropriate convection models: i. Boundary layer effects, laminar and turbulent flow ii. Similarity solutions and non-dimensional parameters iii. Reynold’s analogy iv. Boundary conditions – derivation of energy balance v. Use convection correlations for Nusselt Number7. Understand and model external forced convection heat transfer.8. Understand and model internal forced convection heat transfer.9.
