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.

This lecture continues with unsteady/transient heat conduction, with semi-infinite solids. It shows the four different boundary conditions that are presented in the textbook. An example is done of the freezing in soil and how deep water pipes should be in freezing conditions. The use of EES software is also shown on an introductory level.
