Lecture 20 (2018) HD: Heat Transfer by Prof Josua Meyer

This lecture is the third lecture on heat exchangers. It concentrates on the effectiveness-NTU method. The focus of the lecture is on heat exchangers in which phase change (boiling/evaporation/condensation) occurred. An example is shown of an over designed heat exchanger using condensation and how it can be identified easily and be corrected. The lecture was presented on 28 May 2018. This lecture is Lecture 20 (2018) of approximately 4 lectures that was based on the textbook of Cengel and Ghajar (5th edition) and was presented as part of a heat transfer class to the fourth-year students by Prof Josua Meyer, Head of the Department of Mechanical and Aeronautical Engineering of the University of Pretoria, South Africa.
