How can I get the isentropic efficiency of the turbine

Dear All,

I'm an user of ANSYS CFX in turbomachinery mode. In post processing I'm interested to get the isentropic efficiency of a LP turbine made of a single stage (one NGV and then one rotor).

Do somebody know how get that variable in ANSYS-POST?

Kind regards

Hi,
There is two ways to do it in CFX Post:
1- In Tools panel select Macro Calculator then choose Gas turbine Performance and click Calculate, you can view the report or go to the Expression panel where you find all the performance variables.
2- In Turbo panel define your Turbo regions then click Initialize…..and explore your Expression and Variable lists.
