Rotation of Helix due to fluid pressure in Fluent
 

Hi All,

I have a problem in hand where a helix rotates due to the fluid pressure acting on the walls. I need to find out the RPM and torque of the helix due to the fluid flow. I have to simulate this using Fluent or CFX. I tried Dynamic mesh with 6DOF option in Fluent and hooked a UDF to define mass and moment of inertia to the helix wall. But I am not able to see any rotation of the helix. Please help me on how can I proceed with this problem.

Thanks in advance

Regards,
Hari
