论文摘要
我们报告了从受控的初始扰动中报告了雷利 - 泰勒不稳定性（RTI）的晚期自相似生长常数$α_b$的新颖测量。为此，我们开发了一项激光驱动的实验，该实验在国家点火设施（NIF）上进行了探索，以探索平面界面的深层非线性多模流动力生长。测量值为$α_b= 0.038 \ pm 0.008 $，这与先前报道的2D模拟一致，并且更接近先前报道的3D模拟。这解决了RTI的实验和模拟之间已知的差异。
We report a novel measurement of the late time self-similar growth constant $α_B$ of the Rayleigh-Taylor instability (RTI) from controlled initial perturbations. To this end, we have developed a laser-driven experiment, fielded on the National Ignition Facility (NIF), to explore deeply non-linear, multimode hydrodynamic growth of a planar interface. The measured value is $α_B=0.038\pm 0.008$, which is consistent with previously reported 2D simulations and closer to previously reported 3D simulations. This resolved the known discrepancy between experiments and simulations of RTI.
