摘要
本文将流速分解模型应用于作为超浅海风暴潮的渤海风潮,并讨论了变湍粘性系数的确定。作为一个初步的,但较为成功的数值试验例子,描述了实际风场作用下的渤海风潮,比较了变湍粘性系数模型与常湍粘性系数模型的计算结果间的差异。
As a preliminary and successful numerical experiment, the velocity-splitting model is applied to the wind surge in the Bohai Sea as an example of ultra-shallow water storm surges. And the eddy viscosity coefficient profile is determined. There are remarkable differences between the computations based on the model with a depth-varying eddy viscosity coefficient and the model with a constant eddy viscosity coefficient.
