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 26 - External Forced Convection (3of3): Cylinders, Spheres and Tube Banks |
This lecture is the third lecture on external forced convection. The lecture gives an overview of convective heat transfer on cylinders and spheres. The different types of equations and empirical information are discussed. An example is done of the flow of wind over a steam pipe. A short overview is also given of flow over in-line and staggered tube banks.
