| Abstract: | By means of the measurement technique of the multi position sampling using single slanted and normal hot wire, a intelligent constant temperature hot wire anemometer was used to measure flow field within the vaneless diffuser of a small centrifugal compressor under the conditions of three different rotating velocities. Measurement results of mean velocities, flow direction angle and static pressure recover coefficient of three different rotating velocities are given. Discussions and analysis are made for the measurement results. |
