Hi all,
I am trying to model a body moving constantly in a circle. I tried using a rotating reference frame on the fluid at a speed which equated to 25m/s at my desired radius coupled with a velocity inlet with set angular velocity as shown in the image. I've looked at the reference frame tutorials but can't seem to get it right; the problems I am having are (i have tried lots of different boundary conditions): 1. Outlet not having correct angular velocity - usually causes stagnation or voids which affect upstream flow 2. Total pressure changes with radius while static remains constant - shouldn't this be the other way around I don't know if I am trying to do this the wrong way or missing something fundamental so any help would be greatly appreciated. Thanks |
