I'm working on properly modelling cavitation and I know I have some options, but some very incomplete data. I was hoping I could get some of your guys expert guidance on which way to go.

I would like to model the oil vapor as an ideal gas, but I do not know the molar mass, in fact I have NO clue. With the other properties I have some idea. I know density, mean particle size, dynamic viscosity, and saturation pressure at 90 C, the temperature of isothermal operation.

I know instead of ideal gas I could program in properties vs. pressure. If I somehow make an educated guess at this, would it be better than attempting to use ideal gas, or not? If so, how would I write CEL code for rho(P) for example? I haven't seen much in the literature.

Also, if anyone has any insights on the vapor properties of an oil with density at 90 C of about 800 kg/m^3 it would be of great help.

Thanks all

P.S. any additional tips on cavitation modelling you can add that I may not have asked about would also be greatly appreciated to build the best model I can.
