采用概化模型试验对典型温度分层水库中异重流的运动特性进行研究.首次在实验室内模拟了水库水体的温度分层.试验显示:在特定条件下,在水库模型入口底部加入高锰酸钾溶液而形成的底层异重流沿库底运行一定距离后会从底坡分离,进入与其密度相同的水层后沿水平方向运行形成间层流.根据试验结果分析了温跃层平均密度梯度与分离点深度和间层流厚度的关系. The generalized model test was used to study the movement characteristics of gravity flow in a typical temperature stratified reservoir.The temperature stratification of the reservoir water body was simulated for the first time in the laboratory.The experiment shows that under the specific conditions, The different gravity flow of bottom layer formed by potassium manganate solution will separate from the bottom slope after running a certain distance along the bottom of the reservoir and enter into the water layer with the same density and then run along the horizontal direction to form intercostal flow.According to the experimental results, Relationship between density gradient and depth of separation point and interlayer flow thickness.
