Any body help me!, Impeller simulation problem.

March 5, 2009, 12:12

I have the problem regarding to radial flow close type impeller of water centrifugal pump, for many time I tried to run by single blade with periodic flow k-epilon reslizable, single domain rotaion with 2900 rmp and structed hex mesh type ,simple scheme and the others by second order upwind, but the results is still not convergence both mathmatics, physical and also reverse flow appeared at the outlet pressure.

Any body is expertise in this field please help me, I will send the Case and data files via email for discuss the problem, thank you for your kindly.(thomas_crown20@hotmail.com)

Hi everybody.
I have the same problem with a simply 3D geometry with an impeller in it. I want to see a good velocity profile but i don't know how to set a proper boundary condition. Can anybody help me? Tnx
