how can i set rotor?

[albatross918]

well....i sim the rotor( use motion angular, rotating regions = rpm 20000)

boundary conditions

 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

Hi,

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.

Kind regards,
