摘    要:基于N-S方程,采用深度平均的应力-通量代数全场模型,模拟流场及热水或污染物侧向排入大水体的各向异性的输移扩散规律。模型中采用深度平均的连续、动量、浓度方程进行潮汐流动的数值模拟计算,潮流采用非对称潮流,模拟结果给出了一个周期内流场、污染物浓度场随时间的变化特征。所得的数值结果与他人的模型实验结果非常一致,而较其他结果更合理,说明本模型的合理性和可靠性。

关 键 词:深度平均    应力-通量代数    各向异性    非对称潮流

Abstract:Based on N - S equations, the depth-averaged stress-flux algebraic model is developed to simulate the anisotropic transport and dispersion when hot water or pollutants are side-discharged into large body waters. The depth-averaged continuity, momentum and energy equations are employed, and the tide is asymmetric. The results show the changes of velocity field and pollutant density with the time and the space during one tidal period.
Keywords:Depth-averaged  Stress-flux algebraic  anisotropy  asymmetry
