摘要
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.
