Dear all,

I intend to simulate the problem of the conjugate heat transfer in the rotary condition. I have a brick with heat source that is surrounded by air. both the fluid and solid (brick) are rotating with the same velocity. It is worth mentioning that to check the solution, the amount of the heat transfer in the wall and wall-shadow must be almost equal.

In my case, as long as the rotation speed is zero the results is ok. However, as i active the rotation, i can't converge the energy equation so that there is a considerable difference in the amount of heat transfer in the wall a in the wall-shadow.

in your view, is it better if i changer the solver namely CFX? or is there something wrong with my meshing? or anything else?

Thanks for your kind concern.

best,
Alireza
