REGULATION OF DISTORTION FLOWFIELD BY AXISYMMETRIC TURBULENCE GENERATORS

This paper provides a regulation law for distortion flowfield by axisymmetric turbulence generators, which can meet the demands for simulating the static and dynamic inlet distortions simultaneously. The distortion flowfield is regulated by variation of throat area ratio and working pressure ratio. The experiments show that the absolute deviation of the turbulence regulated by this law is less than 0.01.
