摘要(Abstract):

利用流体瞬变线性化理论与拉普拉斯变换方法求得了带有泵与阀门的管道中瞬变流动的解,以及水击波的传播规律,然后通过数值计算得到复杂管系中因泵的调节所产生的瞬变流动的数值解。
The fluid transient linearization theory and the Laplace transformation are applied to find out the solution of transient flow and the pattern of water hammer wave propagation in the pipes with pump and valve in this paper. Then the numerical solution of transient flow produced due to pump regulation in the complex pipe system are obtained by means of the numerical computation.
