Investigation of the Interaction between the Rotor and Stator of a Transonic Compressor

摘要

An evaluation of the rotor outflow matching to a downstream stator was conducted fora transonic compressor stage. The study compared experimental data and throughflowcomputations of the blading flow field to examine the flow angles and velocitydistribution of the isolated rotor and the stage. An assessment of the data allowedthe degree of interaction and matching of the blade rows to be determined. It wasfound that the rotor flow was only slightly modified by the presence of che statorand that the rotor flow dominated the overall stage performance.
