Hi my frineds,

I am starting to simulate a CENTRIFUGAL FAN in ANSYS CFX 15

I want to calculate the efficiecy depending on the number of blades.

I have made the rotor with SW14 and and saved in IGES format to import into ansys.



I have many questions, first I simulate in ansys with the rotor (left image) or the inside with the flow (right image)?



Second, When import(in step, iges, etc. format) the rotor is broken in half. Why? Its normal?



3. Do I need to create a volute If yes, Why? in SW? Ansys?

I have made some experiencies, this is right?






please nyone can help me answering the doubts? I'm completely lost.

Regards
