Hello, how can I show the device efficiency from in CFX..I have a choice of the efficiency of the expansion and compression but I want the monitor like the picture.
Thanks

Sorry to ask, but what device efficiency are you aiming at? Why not build up a CEL variable with your parameters and monitor it?

It is a radial turbine but I cannot find an accurate expression for the efficiency, could you help me please?
Thanks

Well, this isn't really a cfx problem.

In your case, perhaps it would make sense to include something like a isentropic effiency by simply dividing the Enthalpy differences?!

Or take a look at:https://www.google.de/url?q=https://...Mn_eAIBv1iuueg

Thanks ..The question is how to get the non-isentropic enthalpy from CFX to calculate the efficiency?
Thanks
