    摘要:

    针对明渠交汇区域内水流结构的复杂情况,从明渠交汇口汇流比、交汇角度、床面高差和其他影响因素的角度,综述了明渠交汇口分离区、剪切层、二次环流等很多特有的水动力及掺混特性的研究进展,梳理了物理模型试验、数值模拟研究和实地观测成果,总结了水动力及掺混特性的研究现状。基于目前存在的主要问题,未来应重点研究人工智能算法的应用,植被、密度差、潜流带对掺混特性的影响以及挟沙水流交汇问题中的冲刷淤积影响。

    Abstract:

    This paper reviews the research progress on the unique hydrodynamic and mixing characteristics in open channel confluence areas, focusing on the complex flow structures influenced by factors such as convergence ratio, intersection angle, bed elevation difference, and other parameters. Key features such as separation zones, shear layers, and secondary circulations are discussed. The paper integrates findings from physical model experiments, numerical simulations, and field observations, summarizing the current state of research on hydrodynamics and mixing characteristics. Based on existing challenges, future research should focus on the application of artificial intelligence algorithms, the effects of vegetation, density difference, and the hyporheic zone on mixing characteristics, and the impact of scouring and sedimentation in sediment-laden flow confluence issues.
