Ansys BladeGen: Blade Lean Angles
 

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.

Dear there are very good books available listed below.

"Steam Turbines Design, Applications, and Rerating" by Heinz P. Bloch
Murari P. Singh

These books are available to download freely, search in google. It will answer your all questions.

Thanks Dear for reply and suggest some good book. but i have viewed these books but i did not found clear relation to compute the leading/ trailing wedge angle. if u calculate this kindly send the relation. once again thanks
