| 摘 要： | 有气泡存在时的水锤计算发展了多种模型，其中以Ｅ．Ｂ．怀利所提出的离散模型最省计算时间。由于含气量对水锤有很大影响，而负压波造成的压降会导致溶解在液体中的气体释出。因此在上述模型的基础上提出气体释放——离散模型，认为原来的自由气体及释放出来的气体集中在计算截面上，用特征线法进行计算。计算结果与实验结果作了比较，符合得较好。

| Abstract: | It is interesting to calculate the waterhammer when free gas is existence and many models were put forward. Among them the discrete free gas model presented by E.B.Wyile may be the best one. Because of the significant effect of the free gas on the waterhammer, it is important to consider the release of the dissolved gas, when the reduced pressure is less -than saturated pressure. A gas-release plus discrete free gas model is presented in this paper. It assumes that the free gas and the evolved gas arc lumped at computing sections. Characteristics method is used. The calculation results coinside well with the experimetal. |
