摘要：
Digital time series hot-wire data, acquired in the near field of a turbulent free jet of air issuing from a sharp-edged isosceles triangular orifice, have been post-processed using a phase-averaging procedure to determine the coherent and random contributions to turbulence statistics. The Reynolds number, based on the equivalent diameter of the orifice, was 1.84×105. It was found that momentum transfer by the Reynolds primary shear stress occurs mainly via the coherent primary shear stress.
