摘要
本文采用VOF方法数值模拟涌潮翻越丁坝过程。得到定床情况下丁坝上游任意点任意瞬间的时均流速分布。根据流速分布,采用推移质输沙率的结构式作为冲刷强度的指标,比较不同丁坝剖面形式对丁坝上游冲刷坑强度的影响。
The VOF Method is used to simulate the process of the tidal bore turning over the groin, and the instantaneous velocity at arbitary point upstream of the groin is gained. The format of sediment bed load transport rate is used as the index of erosion intension to compare the effect of the groin section profile on reosion.
