涌潮作用下丁坝附近水流运动特性的数值模拟研究
Study on flow characteristics near spur dikes under tidal bore
摘要
Abstract
A mathematical model of tide flow motion nearby spur dikes is illustrated in this paper.The Reynolds equations and the RNG κ-ε turbulent model are solved by the pressure implicit splitting-operator（PISO） method.The governing equations are discretized by the finite volume method,and the physical pa rameters are arranged on a staggered grid,and the free surface is traced with volume of fluid method（VOF）.The model is verified by the observation data,and the comparison between the numerical results and experimental data is in good agreement.The proposed model has been used to simulate the velocity vectors,free water surface,contours and bore pressures of the flow in the vincinity of a spur dike.It is found that the flow near the spur changes strongly,and bore pressures at different height on the groin rise rapidly at first,and then reach their maximum almost at the same time.关键词
