Abstract

In the current work three-dimensional pow measurements in two types of centrifugal compressor vaneless diffuser were obtained using hot wire anemometry. The first diffuser was conical, designed to give a constant flow area, while the second straight wall diffuser had a constant axial width. Measurements of mean velocity, pow angle and velocity fluctuation level were obtained on eight cross-sectional planes in each diffuser.
