目前对异重流塑造海床形态的研究主要是基于对海床观测资料的简单分析模式,缺乏具有完备力学背景的机理性研究。本文基于完整的异重流厚度积分控制方程,发展了异重流二维水沙耦合数学模型。将该模型应用于异重流塑造深海渠堤等海床形态过程,通过数值算例分析表明:海......

现有大部分异重流层平均数学模型是非耦合模型,不同程度上忽略了其与碎屑物输移以及床面之间的复杂相互作用:数值算法不能圆满地处理复杂地形上可能存在的自加速(急流)与减速(缓流)异重流状态的相互转化;复杂地形上水动力模型的和谐性问题(即模型是否满足C-Prop......

最近对冲积河流多重时间尺度的研究表明:即便是非恒定流条件下,推移质也能够很快地调整到其挟沙力状态,证实了挟沙力概念可以应用于模拟推移质占优的冲积河流过程,从而为推移质饱和输沙数学模型提供了理论基础。本文作为该研究的扩展,采用可以捕捉激波的WAF TVD二阶......
