基于分形理论的流速及含沙量垂线分布规律研究
Study on the vertical velocity and sediment concentration distribution laws based on the fractal theory
摘要
Abstract
At present, the velocity and sediment concentration distributions in open-channel flow are approx-imately solved by using of modern fluid mechanics theories combined with some assumptions, hence search-ing for distributions equations with more theoretical basis and higher reliability is a research focus at all the time. In this paper, the velocity and sediment concentration distributions in 2D open-channel flow are studied from the scaling law of self similarity in fractal theory because the whole distribution of velocity or sediment concentration is similar to partial distribution. The results show that the equations of power form, log form and other forms for velocity distribution can be derived from fractal scaling law, and the equations of Laursen, Rouse and others for sediment concentration can be derived from fractal scaling law too.关键词
