Research output: Contribution to journalArticlepeer-review


The flow characteristics of a vaned radial diffuser typical of those currently used in centrifugal compressors were determined experimentally by using a static diffuser test rig. The vortex test vehicle (VTV) portion of this rig was used to simulate the essential features of the flow leaving the impeller of an actual compressor. The mean flow phenomena at the diffuser entrance and the static pressure recovery along the diffuser passage were determined. In addition, the flow angle and Mach number distributions at several key locations throughout the diffuser channel were obtained. The most notable feature of the diffuse flowfield is the degree of non -uniformity in the inlet/leading edge region. (A)
