The paper analyzes the contribution of the sub-particle-scale large-eddy simulation (SPS-LES) turbulent model on the dynamic behavior of the weakly compressible moving-particle semi-implicit (WCMPS) method. To search a robust WCMPS method configuration, the next models are tested: two pressure gradient models, two Laplacian models and the constrained stabilization technique through the control adjustment of the particle velocity by Xu and Jin (Comput Fluids 137:1–14, 2016. https://doi.org/10.1016/j.compfluid.2016.07.014). Then, for these combinations the influence of the SPS-LES turbulent dynamic contributions on the WCMPS method is analyzed. The WCMPS resultant configurations are applied to represent the physics of two different isolated green water events, produced by incoming bores that were generated with the two-dimensional wet dam-break approach. Numerical results captured well the evolution of the green water events, indicating that the WCMPS method can be suitable tool to represent the complex physics of these phenomena, including the breaking features of flow. Moreover, it is shown that even though turbulence is a three-dimensional phenomenon, turbulent contribution can be observable on the velocity field in two dimensions, having a considerable contribution on the adequate representation of green water amounts.

使用WCMPS方法上的SPS-LES湍流贡献进行湿式溃坝模拟以评估绿水事件

本文分析了亚粒子尺度大涡模拟（SPS-LES）湍流模型对弱可压缩运动粒子半隐式（WCMPS）方法的动力学行为的贡献。为了搜索强大的WCMPS方法配置，测试了以下模型：两个压力梯度模型，两个Laplacian模型以及通过Xu和Jin控制颗粒速度的约束稳定技术（计算流体137：1-14，2016年。 https://doi.org/10.1016/j.compfluid.2016.07.014）。然后，对于这些组合，分析了SPS-LES湍流动力贡献对WCMPS方法的影响。WCMPS结果配置用于代表两个不同的孤立绿水事件的物理过程，由二维湿式溃坝方法产生的入孔产生。数值结果很好地记录了绿水事件的演变，表明WCMPS方法可以用作表示这些现象的复杂物理过程的合适工具，包括水流的破裂特征。此外，已经表明，即使湍流是三维现象，也可以在二维的速度场上观察到湍流的贡献，这对于适当地表示绿水量具有相当大的贡献。
