许多高速水流问题,例如泄流表面的空蚀、水流掺气、能量损失以及水流对建筑物的作用等,都与边界层的发展有关。本文在探索紊流边界层发展规律的基础上,研究了掺气发生点的位置及流速系数计算等溢洪道设计中的几个水力学问题。 Many high-speed water flow problems, such as cavitation of the discharge surface, aeration of the water flow, energy loss and the effect of water flow on the building are all related to the development of the boundary layer. Based on the exploration of the law of the development of turbulent boundary layer, several hydraulic problems in spillway design such as the location of aeration points and the calculation of velocity coefficients were studied.
