Flow Direction Profile
 

Hi All,

Can somebody tell me how I can fix an inlet flow direction profile in a cylindrical coordinates for my rotor inlet boundary condition. I am using also a total pressure and a total temperature.

Thanks

Create a local coordinate system on your inlet face such that the origin coincides with the center point of the face. Use CEL to define the radial flow profile that you desire.

When defining the the inflow BC, select the local coord system that you defined, and the CEL profile function. You can use the preview feature of the BC to confirm that you've got the profile the way you want it.
