Abstract

A lot of work was done in planar cascade tunnel to validate the theory on two generations of unsteady flow type. In the first phase, the frequency of all kinds of work condition was got. In the second phase, the method of sound excitation was used based on the frequency got forward to research the interaction between variable unsteady disturbances. Through comparing the total pressure loss, frequency spectra of flowfield's parameter and aerodynamic parameters of unforced condition with those of forced condition, the results of research confirm that the aerodynamic performance of cascade can improved if the interaction of unsteady disturbs in the flowfield can reasonable organization.
