摘要

The interrelations among different nondimensional groups shown by M. M. Awad are quite correct. The insight provided by the author is very much appreciated.The use of the correct nondimensional group is derived mainly from the physical interpretation of the underlying processes. Whenever possible, an underlying model based on force balance or some such similar approach is recommended. This will help in arriving at equations and correlations that are able to accurately represent the form of the interrelationships among variables. Such an approach was adopted by Kandlikar [1 in modeling the flow boiling CHF, resulting in the following equations from a force balance analysis at the liquid-vapor-solid contact line at the CHF condition.
