| Abstract: | In this paper,the measure method is different from traditional method.Using the total pressure probe,the real total pressures in the boundary layer of cascade blade surface are measured.The flow Mach number is changed in the experiment.Some parameters about the boundary thickness are calculated.The purpose of the experiment is to examine the influence of the inlet flow conditions on the boundary layer of cascade blade surface.The experiment results indicate that the influence of the incidence on the boundar... |
