环境流体动力学数学模型在太平水道潮流场计算中的应用

TIDAL CURRENT CALCULATION FOR TAIPING WATERWAY USING THE ENVIRONMENTAL FLUID DYNAMICS COMPUTER MODEL

采用环境流体动力学数学模型对太平水道潮流场进行了计算 ,计算中用水平方向上的曲线正交坐标与垂直方向上的 Sigma坐标相结合以及三维数学模型二维化的方法。计算结果与实测结果比较表明 :模型较好地重演太平水道潮流场 ,可以用于工程实际中的沿岸及受潮汐影响的水道潮流场问题的计算。

The Environmental Fluid Dynamics Computer Code is used in tidal current calculation for Taiping Waterway in this paper. The calculation combines curvilinear orthogonal coordinates in the horizontal direction with Sigma mapping coordinates in the vertical direction, and it uses a method which transforms a problem from three-dimensional into two-dimensional. It shows that the calculations are in good agreement with the results of the field data. The model can be applied to coastal engineering and waterways affected by the tide.
