首次从理论上较深入地分析了泥沙影响紊流运动的力学机制,指出了泥沙惯性可能是制紊的主要因素。从现有一些试验结果的对比、综合出发,论证了含沙质量与紊动强度、涡动尺度,扩散率、临界雷诺数、利查逊数的内在关系,并提出了计算挟沙紊流特征量及水沙能量分配比的方法,文末据范诺尼槽流试验资料,算得了紊流的各基本特征量。
For the first time, the mechanics mechanism of the influence of sediment on turbulence is analyzed in depth, and it is pointed out that the inertia of sediment may be the main factor of turbulence. Based on the comparison and analysis of some existing test results, the inherent relationship between sediment mass and turbulence intensity, eddy scale, diffusivity, critical Reynolds number and Richardson number is demonstrated. The calculation of sediment turbulence characteristics The amount of water and sand energy distribution ratio of the method, the text at the end Fanoni groove flow test data, calculated the basic characteristics of the amount of turbulence.
