Need help in Rotation CFX
I am new to CFX and i got stuck up with this rotation of sphere about its axis.i searched in google for rotation it says to give immersed solid to my domain.i gave but still it is not rotating..i want to rotate the sphere.Help me with boundary conditions. This is what i gave
Fluid stationary inlet velocity 10m/s outlet pressure Solid rotating and also immersed tried seperately i need a guide from here with explanation..pls pls very tired of trying:confused: |
If the sphere is rotating about its axis then put a tangential velocity on the sphere wall, and use a normal stationary frame of reference. No need to use immersed solids.

Tangential Velocity!
I dont undertood the physics of tangential velocity..this velocity just mover around sphere thats it how could it possible to rotate..????:confused:
|
If the sphere is rotating about its axis the fluid volume is not moving at all, but the sphere has a tangential velocity which interacts with the flow. So you model this as a stationary domain and the sphere boundary is modelled as a normal stationary wall with a tangential velocity.
