用三分量LDV测量壁湍流边界层

Measurements of Turbulent Boundary Layer on a Wall of Water Channel by 3D LDV

本文用三分量激光多普勒测速仪对壁湍流边界层进行了测量，经过数据处理后，给出了各湍流参数的分布曲线，并与Ｄｊｅｎｉｄｉ等的测量结果进行了比较，吻合得很好。结果表明。

The three components of velocity in the turbulent boundary layer on a wall of water channel have been simultaneously measured with a 3D LDV.The results are in agreement with those of Djenidi(1994).The experiments indicate that the 3D LDV is an ideal equipment for investigation of 3 D turbulent flow structure.
