Phase Change

mozart · November 17, 2011, 06:06

Hello All,
I am working on a particel track through a nozzle. The tracking and the partikel flow works right. Now i would like to consider a phase change of the partikel due to pressure and temperature drops. Does anyone has a short step-by-step guide for the basics? I just can't work it out.
Cheers!

There is no "easy way" my friend.
It is a very demanding proccess, but you can use the same model you are using (Euler- Lagrange).
Please read the manual of ANSYS CFX there you will find a ton of information.

I read most of the manual. The Problem I have, is that there is no structered way through the programm. For exmaple what do i have to put in to choose the Lagrange Modell....

Some of the tutorial examples demonstrate langrangian particle tracking.
