摘要
流速分布规律的研究是揭示一般水流和高含沙水流流动特性的关键.本文在回顾以往研究成就的基础上,开展了理论及实验研究.以提出的紊流涡团模式为基础,得出了挟沙紊流流速分布的公式,大量实测资料的检验结果表明,该公式能较真实地描述出一般挟沙水流及高含沙紊流的流速分布变化规律,具有较大的使用价值.
The velocity distribution is the key to the revealing for characteristics of ordinary sedimentladen flow and hyperconcentrated sediment flow.Based on the reviews of former researches,additional studies were conducted using theoretical and experimental approaches.From the proposed model of turbulent eddy flow,a velocity distribution formula was obtained for turbulent sediment-laden flow,and then was examined by a large amount of data. Results indicated that the formula could describe both the velocity distributions of ordinary sediment-laden flow and hyperconcentrated sediment flow.
