Hi Dears

Plz could anyone to help me

I would like to know what is the correct boundary conditions for the flow inside centrifugal compressor with vaned diffuser.

I use star ccm+

I will be very happy if anyone reply me

thanks
best regards

You have to use what you know about the flow.
If you know the mass flow rate or pressure apply this.
Typical BCs for that type of flow are mass flow rate (inlet) and pressure outlet (outlet).

Remember that you may need an interface in accordance with the impeller motion within the fluid.

Regards
