Understanding Turbulent Mixing in Inertial Confinement Fusion

通过使用非常强大的激光在一种名为惯性约束聚变的过程中压缩一个小的氢氚球体，实验者第一次产生了净增益聚变反应。然而，使用最先进的数值工具大大低估了增益，这主要是由于流体不稳定性的增长。了解和控制不稳定增长的水平对于实现更有效的融合至关重要。这一国际合作建议利用计算和实验来提供对内爆和爆炸中混合层的基本了解，提供降阶模型的验证，并为最终能源的发展做出贡献。

By compressing a small sphere of deuterium-tritium using very powerful lasers in a process called inertial confinement fusion, experimentalists have produced a net gain fusion reaction for the first time. However, the gain is significantly under-predicted using the most advanced numerical tools, primarily due to the growth of fluid instabilities. Understanding and controlling the levels of instability growth is critical to achieving more efficient fusion. This international collaboration proposes to employ computations and experiments to deliver a fundamental understanding of mixing layers in implosions and explosions, to provide validation of reduced order models and contribute towards the development of the ultimate energy source.
