FLUENT capability - rotating flow simulation
 

Hi,

Been wondering how well and how much FLUENT simulates rotational flows with and without swirl.

My case is where the wall boundary has a very high rpm (few thousands) and experience tells me that, flow equations tend to unconverge beyond a value of rpm in this case.

Can anyone come up to comment whether my observation is true ?

and if it may be possible in some way to quantify the limiting rpm to convergence without actually running a simulation trail ?

Wiser species may kindly respond.
