本文根据动量原理和伯诺里方程,给出了钢管运行过程中突然破裂后外溢流量变化过程的计算方法(这种方法和试验基本吻合),以及由于流量外溢,管内流速变化(增大)所引起的负水锤计算。
Based on the momentum principle and the Bernoulli equation, this paper gives a calculation method of the spillover flow after a sudden rupture during the operation of steel pipe. (This method is basically consistent with the test.) As the flow rate changes (increases) Caused by the negative water hammer calculation.
