Wet Steam Axial Turbines???

naimishharpal · October 28, 2010, 20:12

I am looking for a commercial CFD software which can simulate Wet Steam Axial Turbines? Any recommendations or suggestions?

Thanks.

Fluent is the best option I offer you
but it has difficulties about convergence in wet steam method

@N.Sharifi: Could you elaborate little bit more on difficulties with ANSYS Fluent at converging solution with wet steam method?
Anyways, any suggestions/recommendations for ANSYS CFX?

I think you have 2 choices as the case may be: 1) if you want to do your problem with FLUENT just read the manual and search for the key word "WET-STEAM" in it. you'll find some material about this and a typical UDF written by the software production group. it is noticeable for you to read the section emphasizing on convergence problems in some cases. 2) if you want to do your problem with CFX just read this tutorial :"steam jet" Good luck.

@NS: Thanks. BTW, I have one more question to ask.
Can 'Wet Steam + Condensation model' can predict the 'formation' of liquid droplets in 4-D (x,y,z,t)? i.e. liquid droplets are not present initially, but they should be formed as the steam passes through blade sections, and later increase in size from 0 to some radius via additional condensation.

absolutly yes.
the aim of this method is just for simulation of liquid droplets formation.
if you read that manual carefully you' ll find some important data related to 'Wet Steam + Condensation model'

after all i couldn't understand what do you mean about your first characters: "@NS: Thanks. BTW,"
