I want to know, which type of boundary conditions should be given to rotating machines case? (turbomachine). I want to simulate a cooling fan, and I want to predict performance curve then which type of boundary conditions should I chose?

Hi,

The boundary conditions have to match reality.

Read the best practises guide on turbo machinery, it has some pointers.
