High speed water jet cavitation
 

Hi guys,

Is there anyone doing similar case of high speed water jet cavitation? I am confusing how to set up the model in CFX 11 since water here is compressible flow but the cavitation vapor speed exceed sonic speed and it is incompressible flow. Is it possbile set a compressbile flow and an incompressible at the same time in the model? I set the vapor as ideal gas but some error happens when running the case. Thanks.
