how to solve evaporation problem in fluent

dkb_bg · September 29, 2011, 00:00

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

This is a classical cavitation problem

use multiphase module - simulate steady state cavitation case and show volume fraction of vapor phase ! you are done.
