摘　　要：采用RNG k-ε湍流模型、PISO算法,将整个流场划分为67.27万个网格,选择标准壁面函数进行壁面处理,对海漫加糙后的流场进行模拟计算,分析不同网格数、不同收敛精度、不同湍流模型、不同流场计算方法对数值模拟结果的影响。通过对比分析,计算结果与模型试验实测结果吻合较好,说明数值模拟方法简捷、高效,能获得理想的数据成果,能较好地用于海漫段加糙后的流场模拟计算研究。The influence of the numerical simulation results on different grid numbers,different residual convergence precisions,different turbulence models,and different flow calculation methods,using the RNG k-εturbulence model,PISO algorithm,the whole flow field was divided into 672 700 grids,wall functions were used to deal with the boundary condition,calculated the flow field of scrap tires in energy dissipation and erosion control under sluice. The calculation results are well agreed with the model test results. It indicates that the numerical simulation technique can calculate the flow field.
