Yes, you're right, the axis of the rotating frame is in the y direction. Why do you say that the vortex is broken is correct? My intention is to let it go through the inner cylinder. Is there a...

Hey Dani, I upload two images with circular interface perpendicular to the vortex axial velocity. In the case for the first image without frame motion in the inner domain, the vortex can go through...

I tried the case with vortex from the inlet and vortex goes through stationary and rotating domain. The vorticity isosirface seems continuous although there is some discontinuity at the interface....

Hi Dani, I would say the solution is converged: first, the thrust on the propeller is converged; second, the vortex strength on the ground is converged. I still think the problem is from the...

Hey Dani, I explain to you my case and you can have a better understanding. I build the propeller in a rotating domain and the rest is stationary domain. My stationary domian is not axisymmetrical...

Replies: 21 Can the interface handle vortex? Views: 2,725 Posted By Yannian Can the interface handle vortex? I want to simulate a vortex going towards the propeller by MRF. I want to know whether the interface between rotating and stationary domain can transfer the vortex? Now it seems that it doesn't...
