Hi every body
I want to investigate acoustic cavitation with fluent6.3, In order to model the effect of sound field, a periodic change pressure(change with time) is imposed on liquid in a region.
The cavitation model which takes into consideration such effects as phase change, bubble dynamics, and noncondensable gases is established. time step is set to quarter period of sound pressure.
But my solution not converge(Specially contiuity) with every change in under relaxtion factor.
can anyone help me in regarding with above problem….
thanks

Hi, I have the same problem. it seems we should not to use the usual methods of solution. now I'm investigating of Helmholtz to introduce the pressure waves within the media.

Hi bahar.s.thanks for your interest ,but What is Helmholtz method???this means that can not be solved by Fluent!!!
