摘要
丁坝是河道整治工程中的主要水工建筑物。为分析丁坝附近绕流情况,并验证二维浅水模型的可靠性。以长、宽、高分别为6m×0.9m×0.76m的模拟计算区域平面二维水深平均浅水方程为基本依据,引入k∧-ε∧湍流模型,对非淹没状态正挑单丁坝附近绕流进行数值模拟,模型计算结果与Nawachukwu等人的丁坝实测资料基本吻合。
Groin is the improvement project of the main hydraulic structures, in order to simulate the sluicing area which proves the reliability of the simulation. Circumfluence numerical simulations are about A A 6 m×0. 9 m× 0. 76 m, in accordance with the general shallow water equation of 2D water depth κ-ε water flow model is introduced. Circumfluence numerical simulations on non-submerged single horizontal groin is conducted. The result of the analysis of the single spur dike coincides with that conducted by Nawachukwu.
