量纲分析用于获得描述双层环境流体中羽流行为的渐近解。发现了一个单一的无量纲参数来衡量密度不连续性阻止羽流上升的能力。实验显示了定义弱和强密度不连续性条件的参数值范围。常数是根据实验数据确定的，这允许定量预测一些扩展层特性。
Dimensional analysis is used to obtain asymptotic solutions that describe plume behavior in a two‐layer ambient fluid. A single dimensionless parameter is found that measures the ability of the density discontinuity to stop plume rise. Experiments show the range of values of the parameter that define conditions for weak and strong density discontinuities. Constants are determined from the experimental data, which allow quantitative prediction of some spreading layer characteristics.
