Both the Bell and Kern methods provide correlations for predicting the heat transfer coefficient and the pressure drop in the case of the shell-and-tube heat exchanger design. Would those correlations provide a fair estimate for heat transfer coefficient and pressure drop for fluids that involve phase change? (e.g., boiler, condenser, etc.) or would it work well for single-phase cases? Some fluids might show different behavior. In this case, can we assume that these correlations as generalized correlations independent of fluids?
In part perhaps but not entirely. You should check out Moisture Separator Reheaters (MSRs), as much work has been done on these and you will find many publications. An MSR is a special type of heat exchanger used in the steam cycle of nuclear plants (nothing to do with the reactor part). I discuss these in Chapter 9 of this book, which will be free on next Thursday (3/16). There is some related code free online. https://read.amazon.com/kp/embed?asin=B078HM16GV&preview=newtab&linkCode=kpe&ref_=cm_sw_r_kb_dp_V7NBW6MW60ND74W4V7TW
Thank you very much for your reply. I will surely go through the topics that you suggested.
Kern's Text gives heat transfer correlations for most situations that are commonly encountered. Single phase and multi-phase heat transfer and fluid flow are very different: orders of magnitude different commonly.
I do not know of Bell's work I'm afraid.
