| Abstract: | The turbulence quantities in the turbulent boundary layer on a wall of water channel have been simultaneously measured with a 3D-LDV and analyzed, and the results are compared with classic distributions. The calculation of friction velocity and the distribution of ed-dy viscosity are also discusscd. |
