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.

Hello Genius people,

pls respond back.

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

Thanks farid. I will surely try this and get back 2 u asap.

You are most welcome Ajit.

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)?

Hello Sanjay,

Thanks for your suggestion. Kindly forgive my ignorance but Is there anyway you can post me a hyperlink for any tutorial for simulating rotary components,please.
