Hi there,
made a research on past posts but I haven't found this piece of information.
Even in google I can find several correlations, but for plate heat exchanger
This time I am searching for some suitable correlations for tube internal boiling in case of flooded systems.
I am trying to calculate either Nusselt number and friction factor - of course with two different correlations -.
Main issue is that I suppose that most of current boiling correlations refer to a complete evaporation, while, in case of flooded systems I suppose to have to refer to an outlet refrigerant quality lower than one.
For this reason I suppose the correlation to be very specific.
Please, can anybody help me in this issue ?
Many thanks
