摘　　要：本文用求解化学流体力学基本方程组的方法研究了不可压自由表面问题,着重引入了流体体积分数技术,建立了水坝倒塌问题的物理模型,运用该技术和模型,计算得到了水流的速度和压力在空间的分布及其随时间的变化,与实验观测一致.Incompressible free-surface flows are predicted by solving the basic equations of chemical fluid dynamics. The concept of a fractional volume of fluid is introduced. The physical model of broken dam problem is given. Prediction of distributions of velocity and pressure and their variation with time are obtained by the recommended methods and model, which are in agreement qualitatively with experimental observation.
