This document outlines a lesson plan for teaching heat transfer over 15 class periods. It covers 8 units: 1) Introduction to heat transfer modes and mechanisms, 2) Steady and unsteady conduction, 3) Transient conduction, 4) Convection, 5) Forced and free convection, 6) Heat transfer with phase change, 7) Heat exchangers, and 8) Radiation heat transfer. Key topics include the heat conduction equation, boundary conditions, fins, the Biot and Fourier numbers, dimensional analysis, empirical convection correlations, boiling and condensation, LMTD and NTU methods, and radiation laws.
