为在沉积沉重的流动的骚乱精力的一个平衡方程根据 solidliquid 被导出二阶段的流动理论。方程为二维的、一致、稳定、充分开发的狂暴的 hyperconcentrated 流动被简化。推迟负担的运动的一个精力效率系数从骚乱精力方程被获得,它被定义为沉积暂停精力的比率到沉积沉重的流动的骚乱精力。实验室实验被进行在 hyperconcentrated 流动调查精力驱散的特征。115 试验性的跑的一个总数被执行,包括有自然沉积的 70 跑, 45 与炉渣粉末跑。沉积暂停精力和流动抵抗上的沉积集中的效果被分析,在推迟负担的运动和沉积集中的精力效率系数之间的关系根据试验性的数据被建立。而且,在 hyperconcentrated 流动的精力驱散的特征被识别并且描述。高沉积集中不增加精力驱散,这被发现;相反,它减少流动抵抗。
An equilibrium equation for the turbulence energy in of solid-liquid two-phase flow theory. The equation sediment-laden flows was derived on the basis was simplified for two-dimensional, uniform, steady and fully developed turbulent hyperconcentrated flows. An energy efficiency coefficient of suspended-load motion was obtained from the turbulence energy equation, which is defined as the ratio of the sediment suspension energy to the turbulence energy of the sediment-laden flows. Laboratory experiments were conducted to investigate the characteristics of energy dissipation in hyperconcentrated flows. A total of 115 experimental runs were carried out, comprising 70 runs with natural sediments and 45 runs with cinder powder. Effects of sediment concentration on sediment suspension energy and flow resistance were analyzed and the relation between the energy efficiency coefficient of suspended-load motion and sediment concentration was established on the basis of experimental data. Furthermore, the characteristics of energy dissipation in hyperconcentrated flows were identified and described. It was found that the high sediment concentration does not increase the energy dissipation; on the contrary, it decreases flow resistance.
