A turbomachine for a compressible fluid is provided which includes a compressor wheel having a plurality of vanes extending from a generally axial flow inlet to a generally radial flow outlet. Adjacent vanes define fluid passageways having a generally axially oriented section near the inlet and a generally radially oriented section near the outlet. Located substantially within the generally radially oriented sections of a predetermined number of passageways is a reference station which has a configuration such that the mean tangential dimension of said passageway at said reference station is no more than about 60% of the circumference of the rotor at that mean radius divided by the number of vanes at that radius. Each reference station serves to effect substantial attachment of the flowing fluid to the surfaces defining said passageway, particularly at low mass flow, and, thus, broaden the usable flow range of the compressor.
A turbomachine for compressible fluids comprising a rotor mounted for rotation about a substantially central transverse axis, said rotor including a hub, and a plurality of vanes mounted on and projecting from one surface of said hub, each vane extending between the rotor axis and the rotor periphery, adjacent vanes coacting to define at least in part a fluid passageway having a generally axially oriented section adjacent the rotor axis and a generally radially oriented section extending from said axially oriented section to the rotor periphery;
