【摘要】 在对某一海域的流场进行数值模拟时,尽量提高目标水域的分辨率是普遍追求的目标之一。本文以胶州湾为例,提出了一个大、小网格嵌套的数值模型,并对海域内的防波堤狭长岛屿等视为线边界进行了数值处理,得到了满意的计算结果。更多还原

【Abstract】 This paper describes a numerical model for water circulation in a water body with grid-nets of different mesh-sizes combined together The coarse grid-ncts are for general circulation,and the fine grid-nets are for particular areas that require higher resolution The model was applied to the Jiao Zhou Bay, with the three harbour areas using fine grid-nets Narrow obstruciions,breakwaters etc are treated us line boundaries. The validity of the model has been proved by comparing the calculated water levels at different points with observations The model appears to be satisfactory更多还原
