| 摘 要： | 将一个三维湍能封闭模型应用于渤海潮流模拟，通过流速分解的初边值方法，计算了渤海全海区潮波系统、潮流结构，结果与观测符合较好。计算同时给出了湍粘性系数和湍动能的时空分布，比较常湍粘性系数和湍的垂直抛物分布及湍能封闭模拟表明，湍粘性系数的不同选取会对流场结构有显著影响。

| Abstract: | A three dimensional turbulent energy closure model is used to simulate the tide in the Bohai Sea. By using a modiffied SCM (Separating Current Method), an initial boundary value scheme, this model can be used to compute the tidal wave systems, the structures of tidal flow as well as the time spacial distributions of the turbulent viscosity and the turbulent kinetic energy. The computed results are in good agreement with the observations. The result reveals that the form of the turbulent viscosity selected has a significant effect on the structure of the tidal flow. |
