Hi, all,

I am using Fluent to simulate the rotation flow field in an vortex Pump(it is similar to an centrifugal pump)with a long outlet pipe. My question is, could I use single rotating frame method? if not, How to build a multiple rotating/ translating reference frames?

Best regards,

Wason

If you have only one pump, you should be able to define a single rotating reference frame. Make sure define a fluid volume in which the rotaing parts are enclosed. You also need to define the rotating parts (walls or solid) the same way. You will need to define rotaing axis and the center coordinates of the rotation correctly. Good luck!
