| 摘 要： | 主要对光滑粒子流体动力学(SPH)法进行研究,建立了大坝表孔泄流的光滑粒子模型。将SPH数学模型应用于拉西瓦水电站表孔泄流中,提出了采用补水边界的方法来满足库区恒定水位条件,模拟了表孔泄流的流场变化及粒子运动过程。通过与物理模型实测的压力值比较,堰表面压力变化基本一致。对模拟结果进行分析,表明光滑粒子流体动力学可用于高速水流的计算模拟研究。

| Abstract: | The paper studies the smooth particle hydrodynamics (SPH) method and establishes model of discharge through crest orifice on dam. The author applies the SPH model to the flow of liquid with free surface on Laxiwa dam, simulates the process of the discharge of the surface outlet. The water recharge boundary is used in the model. The paper gives the an analysis of the numerical pressure and the experimental pressure. The results indicate that it is possible to simulate and research high-speed flow using the smooth particle hydrodynamics method. |
