标题： Free surface flows using inverse smoothed particle hydrodynamics

摘要： 自由表面流问题，包括坝破流中的混合过程和波浪破碎现象，特点是自由表面的大变形。因此，这些问题不能通过解析方法和基于网格的数值模型轻易研究。 本文测试了一种称为无平滑粒子水动力学（SPH-i）求解器的新方法，以研究它在湿床二维坝破流中捕捉波浪破碎和水体混合的效果如何。与实验结果相比，该模型相对较好地捕捉到了破碎和混合过程。 因此，可以推断出所提出的模型预测破碎波的发展和演化以及水-水界面在坝破混合过程中的界面能力已经得到了验证。 显示英文摘要

摘要： Free surface flow problems including mixing processes in dam break flows and wave breaking phenomena are characterized by large deformation of the free surface. As such, they cannot be easily investigated by analytical and numerical mesh based models. In this paper a new method called un-smoothed particle hydrodynamics (SPH-i) solver is tested to study how well it can capture wave breaking and mixing of water bodies in 2D dam-break flows over wet beds. The model captures the breaking and mixing processes relatively well when compared against experimental results. Therefore, it can be inferred that the capability of the proposed model to predict the development and evolution of breaking waves as well as the interface at the water-water interface in dam-break mixing processes has been demonstrated.
