Default CFD for rotary components

Hello everybody,

I am completely new to CFD field, but I did some exercises on normal flows through stationary objects using tutorials in Ansys CFX-11. Now I have a trouble when i am implementing on real term objects. I am trying to analyse airflow for a centrifugal blower as a sucking effect through a heat exchanger. I couldn't find any supportive tutorial to simulate rotary components. Hence i used a multiphase tutorial and I picked concepts of frozen rotor, rotational periodicity etc and tried implementing but cannot succeed for rotational behaviour of air flow. Can any body Pls help in finding a supportive tutorial so that I can have a joy. Thanks in advance.

Hi Ajit, Use Transient Rotor Stator model instead of Frozen Rotor.

hi ajit and Farid I think u should try single rotating domain becoz fluid is air.Then go for Two domain.

if u are trying Frozen-rotor or transient rotor model then u have to go for two domain. I think this problem can be handled in single domain.

well, what is gap between blades and housing (outer vessel)?
