Simulation of cavitation with compressibility of a working fluid

[zzitplay]

Kind and smart people, please consult me.

I am trying to simulate cavitation in a closed volume. Is it possible to simulate cavitation with a compressible working fluid in the Ansys module or other software (as I understand it, compressibility is determined by the modulus of elasticity)?

In Fluent, cavitation models do not work with the сompressible-liquid mode for density - "Both liquid and vapor phases can be incompressible or compressible. For compressible liquids, the density is described using a user-defined function" - you need to write a UDF for density (please share, if you have some), if this has changed in the new versions, please tell me, I did not find the information myself.

In CFX, compressibility seems to be set via Tait EOS, but I have not found information on whether this will work normally with cavitation.

I kindly ask knowledgeable people to share the information.

Yes. You can use the "compressible-liquid" option for the liquid phase density. The vapor phase could be incompressible or based on ideal-gas or real-gas. The compressible-liquid option is similar to the Tait-EOS of CFX that you have mentioned in your post. In the latest versions, you can also use RGP-tables for both liquid and vapor phases with the cavitation mass transfer model.
