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 is the first introductory lecture on external forced convection and the following topics were addressed: drag and heat transfer in external flow, parallel flow over flat plates, friction coefficients (local and average), Nusselt numbers and heat transfer coefficients (local and average), and flat plate with unheated starting lengths.
