Abstract

Centrifugal compressor having flow-control blades in which each of the flow-control blades has a pressure side and an opposite suction side. Each of the flow-control blades includes a main section and an inducer section that project away from an impeller surface. The inducer section is positioned upstream from the main section. The inducer section includes a trailing edge and the main section includes a leading edge that is spaced apart from the trailing edge. The inducer sections are aligned with the respective main sections as the inducer and main sections project from the impeller surface to a designated point above the impeller surface. Each of the trailing edges of the inducer sections and the respective leading edge of the main section form a bleed gap therebetween after the designated point. The bleed gap is configured to permit fluid to flow therethrough from the pressure side to the suction side.
