本文采用godunov型SPH方法对振荡波涌变换器（OWSC）与波浪的相互作用进行了数值研究。利用黎曼解算器计算密度场可以得到更平滑的SPH压力场。因此，可以更准确地估计OWSC上的负载。此外，在SPH方程中加入了RANS k-e模型的拉格朗日形式，以更好地捕捉流动的湍流特征。分别进行了二维（2D）和三维（3D）的SPH模拟，并将模拟结果与实验数据进行了比较。©2013 asme
This paper deals with numerical studies of wave interaction with an Oscillating Wave Surge Converters (OWSC) using a Godunov–type SPH method. The use of a Riemann solver in calculating the density field results in a smoother SPH pressure field. Hence, a more accurate estimation of loads on the OWSC is achieved. Furthermore, the Lagrangian form of the RANS k–e model is included in the SPH equations to better capture the turbulent features of the flow. SPH simulations were performed in both two–dimensions (2D) and three–dimensions (3D) and results for the flow pattern and loads are compared with experimental data.© 2013 ASME
