There was no attempt on my part to discredit any of the cited models. Rather, the intent was to focus on two key points:
After reading Prof. Thome’s discussion, I stand on the commentary made in my Technical Note. My reference to the generic Chen model is not limited to the “superposition model” which he published in 1966. As stated in my Technical Note the generic Chen model is meant to be a class of models, for which the F-factor is independent of heat flux and the exponent “n” is chosen to best fit the data. I believe that the concept of an F-factor that depends only on hydrodynamic parameters and is independent of heat flux is a sound and rationally based concept, which has been applied by a many correlation developers. As stated in my Technical Note, there is very strong support for the Chen proposal that the F-factor...
