Heat Transfer

Heat transfer lectures by Professor Josua Meyer (2014). Topics covered in the lectures include: transient or unsteady heat conduction, convection heat transfer, external and internal forced convection, heat exchangers, thermal radiation including atmospheric and solar radiation. The lectures are based on the textbooks of White (8th ed) and Cengel and Ghajar (4th ed) and were presented as part of a heat transfer class to the fourth year students of the Department of Mechanical and Aeronautical Engineering, University of Pretoria.

Lecture 05 - Transient Heat Conduction: Large Plane Walls, Long Cylinders and Spheres

This lecture continues with transient heat conduction, specifically in large plane walls, long cylinders and spheres. It shows how the exact equation for one dimensional heat transfer is derived for a large plane wall starting with the energy equation. It focuses on the principle of the derivation without doing all the mathematics and specifically why the problem is nondimensionalized.
