对完全发育的明渠流动进行了摩擦速度雷诺数为180的直接数值模拟。自由表面近似为刚性滑动壁。通过对计算精度的验证，得到了各种湍流统计量的预算，包括三重速度相关的预算。详细研究了这些量在自由表面附近的行为，并讨论了建模的意义。
Direct numerical simulation of a fully-developed open-channel flow has been carried out for the friction-velocity Reynolds number of 180.The free surface is approximated by a rigid slip wall.After verifying the computational accuracies,the budgets of various turbulence statistics including the budget of the triple velocity correlations have been obtained.The behavior of these quantities near the free surface has been examined in detail and implication for modeling is discussed.
