Using these formulas and a 1-d LDA, meansquare value of 2-d turbulent velocity fluctuation and Reynolds shear stress have been measured for water flow in a square duct.
用这些公式和一台一维激光多普勒测速计,测量了方形管道中水流的二维湍流速度脉动的均方值和雷诺切应力。

The non-homogeneous metal flow during the extrusion forming process was well controlled by introducing a non-equilibrium parameter of metal flow, the mean-square deviation of velocity (SDV).
