The Impact of Variable Inlet Guide Vanes on Compressor Performance

Abstract

Based on literature review and experimental work at the wet gas compressor rig focus is given to the inlet guide vanes performance and their impact on the impeller stage flow regime. This relates both to dry and wet operating conditions.

1) Based on tests, establish full performance map exposing the IGV impact at dry and wet conditions.

2) From literature and experiments establish wet gas flow regime across the IGV.

3) Document IGV impact on stage (impeller and diffuser) flow regime.
