GENERAL MECHANISM OF TURBULENCE AND ITS APPLICATIONS

In this paper, some important mechanisms of turbulence proposed in literature are reviewed, which include Brown-Roshko's large-scale vortex structure developed in the mixing shear flow, Perry and Chong's 'A' vortex in turbulent boundary layer and the author's general mechanism of turbulence in 3-dimensional turbulent flow with respect to the vortex structure of pulsative vorticity convection and diffusion. The criterion is proposed for distinguishing the flow patterns. The bursting phenomenon near the wall ...
