摘要
冲击点火是一种新型的惯性约束聚变点火方案,该点火方案具有低点火能量阈值、高增益和较好的流体力学稳定性等优点.本文针对冲击点火的物理特性进行理论分析和数值模拟.首先以一维平板模型对冲击波碰撞的物理过程进行理论研究和分析;然后通过辐射流体力学数值模拟对冲击点火的物理特性进行研究,验证理论分析结果,并考察冲击加载时间对点火的影响.
As a novel method to assemble and ignite thermonuclear fuel,shock ignition offers several significant advantages, including low ignition threshold,high gain,and good hydrodynamic stability. In this paper,the mechanism of shock ignition is analyzed theoretically and simulated numerically. First,using one-dimensional planer model,the principles of shock collision in shock ignition are analyzed. Then simulations are performed to study the mechanism of the shock ignition scheme. The simulation results are compared with the theoretically analysis,and the robustness of the ignition scheme in terms of shock launching time is studied.
