Mix flow impeller redesign

Prasad Laxman Kane

Hi,

I am into redesign of a mix flow pump impeller. Outoff the listed parameters which parameters would be most important to consider them for the further CFD analysis using FLUENT,

1. Blade inlet angle 2. Blade outlet angle 3. Angle made by absolute velocity of fluid and blade at inlet and outlet 4. inlet and outlet areas 5. Number of blades

I fill only first two parameters should be considered for the CFD analysis to redesign the impeller.

I need your valued suggestion in this regard.

Thanks and Regards, Prasad L. Kane
