Based on the idea that turbulence is the flow phenomena caused by the movement of vortex, the structures of turbulent boundary layer are discussed. The circulation is the most important factor for characterizing the flow structures. The large scale m

A model calculation is made to interpret the quasi-periodic nature of the large eddies in the outer layer of a flat plate turbulent boundary layer, in that the boundary layer flow is modeled by using a 2D discrete vortex method. The power spectrum of
