摘要：
Aiming at the problem that the Reynolds number cannot be accurately defined for the traditional smooth particle dynamics (SPH), the SPS-δ-SPH method was proposed by using the sub particle scale(SPS) turbulence model to deal with the fluid viscosity. The 2D flow around a cylinder at different Reynolds numbers was simulated with the viscosity treatment by using artificial viscosity, laminar viscosity and SPS turbulent viscosity respectively. The variation of hydrodynamic coefficient under different viscosity treatment methods were systematically analyzed and compared with the calculation results of relevant literatures. The results calculated by SPS model were close to the experimental values at lower Reynolds number, as well as the results were stable at a higher Reynolds number, which showed that the SPS-δ-SPH method is suitable for viscous flow problems.Furthermore, the SPS-δ-SPH is applied to simulate the 3D flow around a surface piercing cylinder and the calculation results with higher accuracy are obtained.The research results provide certain reference value for solving related problems in the field of marine engineering. © 2024 Huazhong University of Science and Technology.
