    Similarity law for the streamwise turbulence intensity in zero-pressure-gradient turbulent boundary layers
    Marusic, I. ; Uddin, A. K. M. ; Perry, A. E. ( 1997)
    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.
