A centrifugal compressor impeller with high exit Mach number (M = 0.8–1.1) & high outlet flow angle (ALPHA 2 = 78–85 degrees) was designed. The objective of this work is to create a real condition for the better understanding of the behavior of the fluid flow in transonic and high swirl flow vaned diffusers. Particular attention was given to the flows located at the rotor–stator interface. The unsteady interaction between impeller and diffuser plays an important role in the compression process, especially in high loaded impellers. Actually, the vaned diffuser has to tolerate the distorted upstream flow due to the jet-wake structure coming from the impeller. Following the impeller design, numerical investigations were conducted for the transonic centrifugal compressor impeller composed of backswept unshrouded blades. The characteristic plots of the impeller resulting from the simulations show a good stable operation.
