该实验通过在一个突然扩大的河道分别对柔性植物、刚性植物水流特性进行研究。通过实验研究发现:(1)无论种植刚性植物还是柔性植物,我们以植物最高点为界其流速分布有明显区别。此外A、B断面与C断面流速分布图型也有明显区别。(2)柔性植物与刚性植物的紊流强度分布出现多转折点多S型分布,并且紊流强弱与植物刚柔性有关。
In this experiment, the flow characteristics of flexible plants and rigid plants were studied respectively in a suddenly expanding river. Through experimental study, we find: (1) Whether we plant rigid plants or flexible plants, we have a clear difference in the velocity distribution between the highest point of the plant. In addition, A, B section and C section velocity distribution patterns are also significantly different. (2) The turbulence intensity distribution of flexible plants and rigid plants appeared multi-turning S-shaped distribution, and the intensity of turbulence was related to plant rigidity.
