Abstract
Mean velocity distributions of fully developed turbulent flows show a similarity revealed by experiments. The theoretical approach of Kármán's similarity hypothesis [1] concerning two-dimensional turbulent velocity fluctuations was based on experiments, but it was criticized on the basis of the generally accepted view that the turbulence phenomena was always three-dimensional. This paper intends to reveal that the mechanical similarity hypothesis is applicable to the 3-D boundary layer flow and a 3-D model of turbulence will be shown according to which the inner mechanism of the turbulence can be represented by a stochastic process including 5 independent probability variables.
