boiling correlation in flooded case

boiling correlation in flooded case

(OP)
Hello,
I read a lot of threads in the forum concerning boiling correlations.
All of them were absolutely interesting and written by experts, but as a matter of fact not completely useful for what I am looking for.
I have to dimension a so called flooded heat exchanger. With respect to standard heat exchangers, in this case I have not at inlet a mixture of liquid and vapor but liquid only and at outlet a mixture of liquid vapor and not superheated vapor.
I am looking for a suitable boiling correlation for determining convective heat transfer coefficient and pressure drop.
I suppose that, because of different inlet and outlet conditions, traditional correlations can't be utilized.
Can anybody help me ?
Thanks in advance !
 

RE: boiling correlation in flooded case

A quick initial observation. Refrigeration heat exchangers usually operate with mixed phase. Sure the inlet and outlet conditions are usually assumed to be 100% liquid or vapour, but in real life there is often some deviation so the inlet or outlet condition may be a saturated mixture.
