changing pressure at outlet boundary conditions for nasa stage 37

ahmed 3li · March 12, 2023, 12:26

I want an advice to know how I can chang the average static pressure at outlet boundary to obtain mass flow outlet for nasa stage 37 axial compressor where I was changing it random by steps like ( 100kpa and then 110kpa and then....) .but I think this isn't the right way.to do, so is there another way?

What are you trying to do?

If you are trying to do a map of compressor performance over a range of pressures, and the simulations are steady state runs then this is MUCH better done using the parametric modelling capability in ANSYS workbench, or the performance map capability in CFX.

Opaque and ahmed 3li like this. __________________ Note: I do not answer CFD questions by PM. CFD questions should be posted on the forum.
