Bladegen Angle Notations

subodh_12 · December 13, 2018, 15:30

Dear all,

I'm having trouble understanding the angle notations used in BladeGen. I looked through the ANSYS Help section and that is also not of much help here. I have to simulate the impeller and inducer section(I want to simulate them individually) of the centrifugal turbopump feed system used for rocket applications.

Inducer-Summary.png

I have attached a summary of the specifications of the impeller and the inducer [For more detail please refer to Pg. 217 of NASA SP-125]. How can I develop a BladeGen model given that I have the velocity triangle at the inlet and the discharge? Is this enough to accurately model in BladeGen, and if not then what else is needed to be calculated?

I thank you for your help in advance!
Cheers!
