The simulation of a centrifugal compressor with holed casing treatment

gongmq · December 9, 2017, 04:36

Hello everyone,
I’m trying to simulate a centrifugal compressor with holed casing treatment, but I don’t know how to set the interface between casing treatment and the impeller. Can you help me? Any help will be appreciated!

I do not understand what casing treatment you are talking about. Please attach an image.

Have you done the CFX tutorials? The ones on rotating machinery will be relevant here. You can get them on the ANSYS Customer website.

Hello Ghorrocks! Thank you so much for the reply. I have attached the image of casing treatment. Please take a look at it and help me solve the problem.

Explaining what the image shows might help. What do those external holes do? Where does the fluid go?
