摘要
以流函数涡度方程为控制方程建立数学模型 ,模拟了不同流量级下不同长度正交丁坝附近的局部流场 ,并将模拟结果与室内流场实验结果进行了比较和分析 ,两者吻合较好 .
A mathematical model of local flow field around spur dike is established by using the flow function equation and vorticity equation. Based on this model, local flow fields around the normal spur dike under various discharges and various dike lengths are simulated. Compared the simulating results of the flow fields with the indoor experimental results of ones, the both are fairly coinsident.
