Effects of non-local electron thermal transport on ablative Rayleigh-Taylor instability

AbstractA two-dimensional full Fokker-Planck (FP) simulation code coupled with an ideal fluid equation has been constructed. This code was applied for the numerical simulation of the Rayleigh-Taylor (RT) instability on the directly driven ablation front. The simulation results show that an accelerated thin foil is preheated by the non-local electron heat transport, the ablation front density is depleted, and the linear growth rate of the RT instability is suppressed strongly. By investigating the mode structure in the simulation, it is found that the peak of the eigen mode shifts toward the corona region by the non-local heat conduction effects. This is the reason why the growth rate is reduced.

二次元完全フォッカー・プランク(FP)シミュレーションコードを、理想流体方程式と連成させて構築した。本コードを、直接駆動アブレーション面におけるレイリー・テイラー(RT)不安定性の数値シミュレーションに適用した。シミュレーション結果は、非局所電子熱輸送によって加速される薄膜が予熱され、アブレーション面密度が減少し、RT不安定性の線形成長率が強く抑制されることを示している。シミュレーションにおけるモード構造の調査により、非局所熱輸送効果によって固有モードのピークがコロナ領域へシフトすることが明らかになった。これが成長率が低減される理由である。
