CFX Pre Domains for centrifugal pump

MechKim · September 24, 2012, 05:46

Hi,

Im a student and am having big troubles with my CFD analysis of an artificial heart pump. I ultimately need to determine the shear stress induced on the fluid by the rotating vanes.
I have extracted the fluid volume of the pump, and have meshed it (i need to do a hex mesh, but iv got a tet at the moment...) But i seem to be having issues defining a rotating and a stationary domain in CFX Pre...

Here is a link to my file if anybody would be able to have a quick look and see what i need to do, or fix it up for me. Im an ANSYS novice and am completely stuck

cheers,

depends on which ressources you have

Do you have turbogrid and ICEM license?

Do you want to make a transient or steady-state simulation?

Normally, you need two rotor/stator interfaces. First @impeller inlet, second @cross section between volute/impeller outlet
