Hi ! I read on the Simscale website that the reference pressure in the cavitation model is used to calculate the density. Is this pressure the same as the inlet pressure in the pump or does it have a different meaning? I am asking this question because I used the cavitation model in cryogenic fluids and I believe I made a mistake in this value as I did not change it.
Hi @t_vaggos007, thanks for posting on the forum!
I can double check this with the team, however, from the documentation:
Cavitation is typically modeled as an extension of the variable density Navier Stokes equations with an additional transport equation for the gaseous phase. This is coupled to the liquid phase via a set of source and sink terms based on local conditions such as pressure, turbulence, temperature, and more. A phase fraction term is introduced, representing the given content of a cell that is occupied by either gas or liquid.
Please note that the Cavitation model is only available on the Multi-purpose solver, which in turn is only available to our professional paid users.
Let me know if this helps!
Cheers

Τhank very much. I don’t have some project to run. I just want to understand the pressure on the image that I circled
I just want to know theoretically if it’s possible.
Hi @t_vaggos007, from my understanding this is simply the baseline pressure from which you retrieve the fluid’s properties
Thank you !
