摘要

The experimental investigation is conducted with LDV and hydrogen bubble technique in water flow. The shear layer thickness, the vorticity thickness, the maximum value of turbulence intensities, the turbulent coherent structure, the variations of wall shear stress and the boundary layer shape factor are obtained. In the redevelopment region, the detailed analysis is first made for the streak structures in the near wall region and the turbulent boundary layer is formed at (x-x_r)/h= 20.
