| 摘 要： | 用雷诺方程按有限分析法计算了平面闸槽区附近的平均紊流场——包括平均 速度分布，涡量分布和压强分布等。计算表明，当来流流速ｕ∞不同时．压力系数Ｃｐ 分布是不同的。根据空泡动力学理论，计算的初生空化数和估计的空比初生位置随ｕ∞ 而变．计算结果基本上和实验相符合。

| Abstract: | The finite analytical method is employed to solve Reynolds equations and the results of the mean turbulent flow field near the two-dimensional slot of gate are given. The results show that pressure coefficients are not the same for different velocities in the entrance. According to bubble dynamics, different numbers and positions of cavitation incipience are got for different velocities in the entrance. The results of computations basically correspond with experiences. |
