一种有限体积悬沙输运模型在苏北辐射沙脊群海域的应用
A sediment transport numerical model with finite volume method using in the radial sand ridge field of South Yellow Sea
摘要
Abstract
Suspended sediment transport is an important factor for the evolution of the offshore area. A large amount of suspended sediment is transported under the wave and current action in the radial sand ridge field of the South Yellow Sea. Based on triangular grid, each single triangle element was seemed as the control volume to make Gauss line integral and discrete process. By the format of second order MUSCL Reconstruction and Roe flux, the space discretization of the governing equations was made. With the method of time discretization which based on the format of one⁃order forward difference and the equilibrium treatments of diffusion term,the two⁃dimensional water and sediment mathematical model with finite volume and high precision was established for complex terrain and hy⁃drodynamic condition, and the water flow of the radial sand ridge field in the northern part of Jiangsu province was numerically simulated.关键词
