how to solve evaporation problem in fluent
 
Hi all,
I am solving a fluid flow problem in a narrow diameter pipe. Due to decrease in pressure fluid starts evaporating and some phase(liquid to vapour) change is taking place.so how can we show the vapour bubble formation?

thanks

fluid flow
 
This is a classical cavitation problem :) use multiphase module - simulate steady state cavitation case and show volume fraction of vapor phase ! you are done.

Thank you CFDtoy
i will try cavitation model,
