Default pressure change and angular velocity
Posts: n/a
Hi Everyone:

I am simulating a rotor model. For a certain boundary condition,when I specified different angular velocity for the rotating domain,I got different pressure change between the INLET and OUTLET.Could anybody tell me what is the relation between the pressure change and the angular velocity? Thanks in advanced.

I'm gessing that it might be due to the work input of the rotor.

Hi Robin:

Thanks for returns.I think your guess is right. Then I want to know which of the angular velocity is suitable for my simulation.Can I choose it according to the pressure change or just choose the angular veloctiy from experiment?

Best Regards Mangnan
