Design of pump-out vanes

[BasakAbhishek]

Hello,
Can anyone point to any publication having the guidelines for design of pump-out vanes in radial centrifugal pumps?
Thanks!
Abhishek

Did you try Google, took me about 30 seconds to come up with a number of links, a couple that looks quite interesting.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Dear Artisi,

yes I did, but couldn't come up with equations or design rules. All I could get were some CFD calculations for some specific impeller designs.m What I need are mathematical formulas (ideally) or design guidelines.

Does this help

Check out a Munson Fundamentals of Fluid Mechanics section 12.4. You can google around for it. It has formulas for theoretical performance based on impeller geometry.

I have messed with the formulas quite a bit, plotting them against manufacturer curves and have never developed a fit close enough to use reliably.
