Measurements were canied out close to the leading edge of vane diffuser of a centrifugal impeller to study the flow behavior from impeller outlet to throat at different flow coefficients. The flow behavior is characterized in terms of pressure recovery coefficient from leading edge to throat and variation of Mach number and flow angle near throat. The unsteady static pressure variations at impeller outlet, leading edge and across the throat of vane diffuser were also measured to characterize the flow. Some salient features of the measurements are discussed in this paper.
