Hi every one

I have calculated NPSHR for 20 sets centrifugal pumps by using cfx 12, but the predicted results are not satisfied when compared with experimental value.
I want to kown if anyone have calculated the NPSHR of centrifugal pump.how about the predicted results?

and, how to setup the cfx pre for predicting NPSHR?

THANK YOU very much.

Have you read the best practises guide for pumps? It is installed as part of the documentation. It has a lot of good hints on pump simulations.

HI ghorrocks

thank you for your reply.
I have read the documents about the pump, the predicted head and efficiency of centrifugal pumps are well,but the NPSHr of pumps are bad.so I want to kown the the others predicted results and set process in cfx pre.
