What boiling model parameters to choose
 

Hello!
I am modelling in FLUENT a boiling flux through a vertical channel. I am using Eulerian model with RPI for boiling.
My BCs are: velocity inlet (with a defined profile), pressure outlet and Wall (temperature). Temperature of vapor is fixed to saturation temperature.

I have not find useful references about which boiling model parameters are better for this case. What would you recomend me to choose for Bubble Departure Diameter, Frequency of bubble departure, Nucleation Site Density and Area Influence coefficient?

Any advice will be apreciated.
