Default Rotating solid zone
Posts: n/a

I am trying to model 2-D axi-symmetric heat transfer problem where the fluid is flowing over a rotating cylinder. There is one fluid zone and a solid zone. I have used the coupled implicit solver so that the velocity formualtion is in absolute frame of reference. I am able to give a rotational velocity for the solid zone as 1000 rad/s. But I have the following doubts

1.Do I need to give the same solid rotational velocity for the fluid zone also?

2. Should I give rotational velocities for the walls of the solid zone under the MOMENTUM tab?, infact, the momentum tab is not accessible at all for the solid walls for this case as I have the solid zone.

3. How can I get the tangential velocities (in the direction of rotation of the solid) of the fluid particles for the post processing?
