Axisymmetric swirl CHT with MRF
I'm doing CHT analysis on a axisymmetric swirl case.
I have coupled both solid and fluid volumes. I have specified angular velocity (rpm) to the solid zone.
Is it necessay to input the rotation to walls of the fluid where it is coupled. Will the rpm input at the rotating solid take care of the rotation of the fluid wall?
When I do not input rpm on wall of fluid, the swirl equation does not solve. Why is it?
Can someone help. Thank you.
