根据湍流封闭理论,建立一种适用于正压浅海湍流运动的雷诺应力封闭模型(RSM),以代替目前三维浅海动力学模型中普遍采用的湍粘性系数的传统假设。通过直接建立并模化f—平面上正压海洋的雷诺应力传输方程,分别得到的微分形式和代数形式的RSM方程组。并讨论了进行数值计算所需要的边界条件。利用该模型可以进一步研究浅海潮流、风暴潮流及风海流等浅海流动的三维结构和湍流特性。 According to the theory of turbulent flow closure, a Reynolds stress closed model (RSM) suitable for turbulent flow over a shallow pressure sea area is established to replace the traditional hypothesis of the commonly used turbulent viscosity coefficient in three-dimensional shallow-sea dynamic models. By directly establishing and simulating the Reynolds stress transfer equation of the positive pressure ocean on the f-plane, the differential form and algebraic form of the RSM equations are respectively obtained. The boundary conditions required for numerical calculation are discussed. The model can be used to further study the three-dimensional structure and turbulent characteristics of shallow-sea flow such as shallow tidal current, storm current and wind current.
