湍流Rayleigh-Taylor混合引起的混合质量的准确预测对于许多自然现象和工程应用具有重要意义，但迄今为止还没有建立起基于此的定量理论。在这项研究中，我们建立了一个定量的理论来预测它的演变在任意密度比的密度比不变的平均物种的轮廓，这是最近发展的理论，这封信中提出的湍流波动的封闭模型。得到了混合质量与混合宽度之间的转换公式，导出了归一化混合质量随密度比的定量变化。在不同密度比下，理论计算结果与直接数值模拟结果吻合得很好。该研究为惯性约束聚变等实际工程应用中混合质量的定量预测提供了参考。
The accurate prediction of mixed mass induced by turbulent Rayleigh-Taylor mixing is of fundamental importance for many natural phenomena and engineering applications; however, no quantitative theory based on it has been established yet. In this study, we establish a quantitative theory to predict its evolution at arbitrary density ratios by combining the theory of density-ratio-invariant mean species profiles, which was recently developed by us, and the closure model for the turbulent fluctuations presented in this letter. The transformation formula between mixed mass and mixing width is obtained; in addition, the quantitative variation of normalized mixed mass with respect to the density ratio is derived. The theoretical results agreed very well with the direct numerical simulations at varied density ratios. The study sheds light on the quantitative prediction of mixed mass in practical engineering applications such as inertial confinement fusion.
