本文用光滑粒子流体动力学(SPH)方法求解二维溃坝问题。主要的重点是在墙上的影响过程中的压力评估。详细介绍了所采用的数值计算方法和压力估算方法。流的运动学和动力学的数值结果与文献中的实验数据进行了比较。所使用的方法的能力和局限性进行了讨论。
This paper presents a solution of a dam break problem in two dimensions obtained with smoothed particle hydrodynamics (SPH) method. The main focus is on pressure evaluation during the impact on the wall. The used numerical method and the way of pressure evaluation are described in detail. The numerical results of the kinematics and dynamics of the flow are compared with experimental data from the literature. The abilities and limitations of the used methods are discussed.
