The effects of vaneless diffusers and vaned diffusers with different entrance installation angles on a centrifugal compressor basic stage were studied with numerical calculations and tests.For compressor basic stage with vaneless diffuser,inner flow-field characteristics at nearsurge point,design point,and near-choke point were analyzed,showing that vortex existed in the inlet and outlet of impeller blade and back of reflux blade at near-surge point while flow state was good at design-point and near-choke p...
