Good morning guys,

I require your help to understand how to set correct values of k & omega for a centrifugal fan.

I understand that we have to calculate coefficient and add this values to boundary conditions but to do that we need the hydraulic diameter. In may case, I don't know know how to do because the model is according to the attached picture.

How should I do to get a correct hydraulic diameter with this inlet ?

Thank you in advance for your help.

Best regards,
