| 摘 要： | 建立了平面二维潮流场模型,采用MADI有限差分方法进行离散求解,利用动边界处理边滩以及心滩随水位升降产生的边界变动问题,对工程海域的潮流场进行数值模拟,并采用两套网格计算方案、使用加密网格,深入进行潮流场的研究分析。验证结果表明,计算的潮位和潮流过程与实测过程吻合较好,为海龙湾工程开发利用提供了科学依据。

| Abstract: | This paper sets up a two-dimensional current numerical model using the MADI finite difference method,applies the moving boundary to solve the problem of mobile boundary with the water level,and conducts a numerical model to simulate tidal current of the engineering area.In order to research further the tidal field research,this paper uses two sets of grid computing solutions and refined grids.The result and its verification show that the calculated process of the tidal level and current coincide fairly well with the field data,and it provides a scientific basis for the development of Hailong bay. |
