本文提出了两类与水锤控制密切相关的水锤反问题,构造了一种判别函数,在原问题有唯一稳定解的条件下,用此判别函数可以确定出反问题解的范围,并给出了具体求解方法。依据水锤反问题为理论基础,建立了水锤控制理论。对两种应用实例进行了水锤控制的数值模拟,并给出了数据和相应的曲线。理论分析和数值计算结果表明,用求解反问题的方法来进行水锤控制是一种准确可靠而简便易行的方法。
In this paper, two types of inverse problems of water hammer, which are closely related to water hammer control, are proposed. A discriminant function is constructed. Under the condition that the original problem has a unique stable solution, the discriminant function can be used to determine the scope of the inverse problem and gives The specific solution. Based on the inverse problem of water hammer as the theoretical basis, a water hammer control theory was established. The numerical simulation of water hammer control is carried out on two application examples, and the data and the corresponding curves are given. Theoretical analysis and numerical results show that water hammer control is an accurate, reliable and easy-to-use method to solve the inverse problem.
