Hi Muhammad,

There are a few number of studies on simulating the evaporator and condenser (boiling and condensing) especially refrigerants. For conducting the simulation, it is very important to use the appropriate correlations according to the heat exchanger's configuration (type). As you said, these correlations are not widely available. These are two useful articles which use the correlations for the plate heat exchanger and both boiling and condensation of refrigerants based on experimental correlations developed by Uehara and Nakaoka between the 1980s and 1990s which can also be seen as well. These articles are:

I hope this helps you

Thanks for the response. There are number of correlations for pure fluids  for flow boiling and condensation in plate heat exchanger, e.g.

I was looking for correlations for mixture, for example mixture of Isobutane and Pentane etc. 

Thanks for your time and response, I appreciate your help.

Hi Muhammad,

Thank you for explaining your question. Yes, I totally agree with you that there is a gap in the correlations describing the flow pattern of the zeotropic fluids which have unfixed boiling temperature. It needs some experiments to generate these correlations. However, I had a look to your article studying the plate heat exchanger configuration with passages are almost in a circular shape. I am not quite sure what will be the deviation but using the tube correlations may give a rough estimation for your needs.

Best wishes

I agree that both tube and plate will have different flow pattern but I would advise you to use the tube correlations in systematic way and then try interpret your results with help of existing literature, this will be your contribution !!!

Khaled Hossin and Shazia Farman thank you for your time and help. I will use the tube correlations  as the available authentic source.
