Hi,
Can anyone help me out!! Done CFD simulation on pump .. got pressure difference and calculated head, But now I need Torque for efficiency calculation. How to obtain Torque at different mass flow rate in CFD?
Thanks

Which code are you working on? It seems to be a trivial application.. haven't you had any luck with tutorials or searching a bit on the forum??

Hi,
I have used CFX. I couldn't find any information relevant for my condition. I have got pressure difference for Head calculation but now searching for CFD output for Torque on impeller.

I do not have access to a CFX license anymore but if I remember well, you can load the results to CFD-Post (if you have a license for CFX, you should automatically have also CFD-Post). There you can go to Calculators -> Function Calculator and choose torque and a specific location where you want to calculate torque.

Fluent has the capability to report the torque directly in the solver in Reports -> Forces -> Moments. You can do the same in CFD-Post as well, of course.
