Radius-dependent pressure drop

aqstax · March 20, 2012, 18:59

Hi,

I have a few questions regarding the fan boundary condition:

1) How can I impose a pressure drop across the fan as a function of both radius and velocity?

2) Would it be possible to achieve (1) using many concentric fans?

Currently I'm attempting to simulate many concentric fans with a k- $\omega$ SST model, but k keeps diverging. I'm not sure if it's because of having concentric fans or something to do with other aspects of my modeling. I would appreciate any help. Thanks!

to anyone reading this, apparently the above mentioned method couldn't work with k-w SST. But I'm running it with standard k-w and it seems to be working fine.
