摘要：
A similarity relationship is proposed to describe the streamwise broadband-turbulence intensity in a zero-pressure-gradient boundary layer. The formulation is applicable to the entire region of the flow beyond the viscous buffer zone and is based on the attached eddy hypothesis, the Reynolds-number-similarity hypothesis and the assumed existence of Kolmogorov eddies with a universal inertial subrange, Experimental data of the authors and those from various published works covering a large Reynolds number range are investigated in light of this formulation, (C) 1997 American Institute of Physics.
