| Abstract: | 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. |
