A finite difference method is developed for computing the two-dimensional transient potential flow generated by an impulse on the free surface.
本文提出计算二维非定常位势流动的有限差分法，流动是因自由表面任意瞬间扰动所产生的。
In tailrace tunnels of large hydropower station, a transient mixed free-surface-pressure flow may occur, which has a complex effect on the stability and transient of the power plant.
大型水电工程的尾水隧洞中可能会发生明满交替流动，给电站过渡过程带来很大影响，需要建立合理可行的明满交替流动数值计算模型。
