well....i sim the rotor( use motion angular, rotating regions = rpm 20000)
pipe = air
rotor, stator = steel
inlet,outlet = 0pa or inlet 500m/s outlet 0pa
motion or rotating regions = 20000rpm
but it doesn't flow, like that image
Wind is always a turn around an object, Not the wind blow back
how can i set this rotor? using periodic bounary contions? but i can't set that
pls check this
In the first instance, you have no inlet duct.
I suggest you might like to read this guide on how best to approach these types of models.
