Boundary conditions for rotating fan
 

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.

hi your giving CFX-11 KNOW, 1)INLET MASS FLOW IN THAT WILL GIVE CYLIDRICAL BOUNDARY CONDITIONS. 2)INLET TEMPERATURE 3)OUTLET PRESURE(MEANS AVARAGE OUTLET PRESSURE
