急流控制是六十年代以后在苏联发展起来的。长期以来,水工水力学的研究主要依靠模型试验,由于模型试验的固有特点,所以,人们设想用水流数学模型来代替物理模型,而急流控制即以这一设想为基础,以流体力学基本理论为指导,开展研究工作的。我们知道解流体力学课题存在着正命题与逆命题两种解法,“急流控制”就是运用解逆命题方法解水力学问题。概括地说,当起始水流参数巳知时,变换明渠某段的几何形状,使 Rapids control developed in the Soviet Union after the 1960s. For a long time, hydraulic hydraulics mainly relied on model tests. Due to the inherent characteristics of model tests, people envisaged using mathematical models of water flow instead of physical models. Based on this assumption, rapid flow control is based on the basic theory of fluid mechanics As a guide, carry out research work. We know that there are positive solutions and inverse solutions in fluid mechanics. “Rapid control” is the solution to the problem of hydraulics by using the inverse proposition method. In summary, when the initial water flow parameters are known, the geometry of a section of the open channel is changed so that
