摘 要:An analysis of the experimental results obtained by laser two focus anemometry in the rotor-stator inter-row region of a high-speed high-pressure centrifugal compressor is presented with the aim of quantifying the unsteady effects of the rotor-stator interaction. Two complementary methods are used. First, the results are analyzed in terms of the time-averaging procedure developed by Adamczyk. The purely time dependent correlations of the velocity components are quantified. They show that the unsteady interaction is mainly due to the splitter wake-vane interaction. Then, it is shown that the rotor-stator interaction produces spatial harmonics which are identified as spinning modes by means of Fourier series.
