Understanding Turbulent Mixing in Inertial Confinement Fusion

点击翻译按钮获取中文摘要

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.
