摘要
在近海尾闾河段,由于水流和边界条件的特殊性,分别用一维和二维模型计算河道水面线与流场分布是十分必要的。在尾闾河段上游区域,运用一维模型计算相对狭长河道水面线的沿程变化情况;在近海宽阔水域运用二维模型模拟流速场及水位在挡潮闸附近的动态分布特征。本文对尾闾河段的一、二维模型及水流参量在其交界面附近的耦合处理进行了探讨,并应用于尾闾河段的实例计算。通过调试验证及预测计算,说明该耦合模型能够较好地处理邻海区域的水力计算问题。
It is necessary to simulate water level curve and flow field distribution respectively with 1-D or 2-D model according to the characteristics of the flow and boundary in estuary area. The 1-D model is applied in the upstream section to sireulate water levels along the river, while the 2-D model is used in the area round estuary to calculate flow field including water levels and velocities. Basic theory and coupling conditions between models of 1-D and 2-D have been discussed, and applied to an instance. Through the comparison of the calculation results and the historical data, it proved that the coupling model can fit the specialty of flood and tidal current well.
