摘要
鉴于钱塘江涌潮水流复杂多变和带有自由表面的情况,采用VOF方法追踪自由表面,考虑各向异性,用修正的K-ε模型封闭Reynolds方程,用施主-受主法求解流体体积函数控制方程,计算了涌潮冲击丁坝时的压力场和自由面状况,并与现场实测值进行了比较,取得了良好的效果,为涌潮的小尺度数值模拟提供了借鉴的经验。
In view of the flow complexity and free surface of the Qiantangjiang River tidal bore, the volume of fluid (VOF) method is used to track the free surface, the modified K-ε model is used to close the Reynoids equation in consideration of the anisotropy, the donor-acceptor method is used to solve the governing equations of fluid volume function, and the pressure field and free surface with the tidal bore impinging the spur dike are then computed. Finally, the comparison between the computed values and the observed values is made, and it is shown from the comparison results that the numerical simulation has got good results and provided referential experience for the small-scale numerical simulation of tidal bore.
