弯曲河道水流的研究现状

水在流动的时候受边界条件影响很大。弯道水流是工程实际中经常碰到的一种水流形式。由于弯道特有的几何特征和几何条件,其水流特性与顺直河道有显著的不同。弯曲型河流的水流运动研究包括流速及流速分布、比降、流场分布、环流运动、紊动特性等。单个的独立弯道中水流结构方面的研究已经比较成熟,文章对此进行了系统归纳。而连续弯道水流结构研究的成果还不多见,针对目前该领域研究中存在的问题提出了一些看法与建议。

Research situation of water flow in bend reach

The hydraulics characteristics of flowing water are affected by boundary conditions enormously.The bend-flow is one of the most familiar forms in hydropower projects.For the special boundary condition and geometry profile of meandering river,its characteristic of flow is different from the flow in regular channel.The research about the bend-flow includes velocity,the distribution of velocity,slope,the distribution of flow,circumfluence of flow and the characteristic of turbulent.The research about flow in s...
