I am new to this website. I have started studying Centrifugal Pump, meanwhile i try to understand BladeGen. I have understood different terminologies related to software and theory. I have understood the theta angle, beta angle but i am unable to understand how ansys calculates blade lean angle. I am totally confused. I have read the help file defining the blade lean angle gamma_r and gamma_z but the way ansys calculates these angle are different. I used all those formulas ansys gave in help file but they are never matched with ansys *.dat file (created by right clicking on the theta or beta graph and opening with microsoft Excel 2007).

I also try to search on google and in different books but i could not find lean angle.

Please someone help me with this.
