Expander curve at different IGV position

[DieguitoI]

How expander performance curves are affected by inlet guide vane position? I mean, I have design curves for this expander kg/h vs % isentropic and kg/h vs kW at different velocities, it is possible to obtain at least qualitatively curves at reduced IGV opening?

ask the expeander mfg for the information you seek; preferably an engineer that can help you.
