flow through impeller
 
Hi, I would like to know if somebody managed to get a converged solution for a 3D turbulent flow through a centrifugal impeller of a pump, using fluent?

Do you want a converged or a correct solution? Just getting a converged solution is very easy ;-)

(1). Yes, Both Fluent and CFX-TASCflow can be used for the radial turbine/pump impeller flow. (2). Since the flow is highly 3-D, it is hard to know whether the solution is accurate or not. (3). It is also very difficult to do measurement. (most available data were performed for 2-D configuration)

Thank you Joern Beilke and John C. Chien for your answers, indeed I'am getting converged solutions but they don't make any physical sense at all. I'll keep on trying.Ciao.
