Abstract

In order to measure a complicated unsteady 3D subsonic turbomachinery flow field by use of five-hole pressure probes and a multisensor hot-wire probe, a computer aided measurement system was built up and developed. Long experiences acquired by us and by other research institutes in various experimental studies were taken into consideration as measurement rules in the system. Using the present measurement system, the 3D unsteady flow fields in turbumachinery were determined. The automatic measurements were performed satisfactorily even in the downstream rotor flow region. From the experiments, it is concluded that the quality of the measurements of the unsteady 3D flow field behind a rotor is improved greatly by means of the proposed computer aided multisensor system.
