| 摘 要： | 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.

| Abstract: | The kinematic characteristic of density flows in thermally stratified reservoir is experimentally studied using a generalized model.The simulation of thermal stratification of reservoir water is achieved under laboratory conditions for the first time.The experiment shows that under certain conditions,the underflow formed by adding potassium permanganate solution at the bottom of reservoir model inlet will move along the reservoir bottom until it arrives at its depth of neutral buoyancy and separates from th... |
