摘要: 利用水平集方法和三阶本质无振荡(ENO)方法研究了流体力学界面不稳定性和激光烧蚀驱动内界面不稳定性数值模拟,并用数值算例与LARED-S程序的运算结果进行了比较.数值结果表明此方法计算惯性约束聚变激光烧蚀驱动内界面不稳定性的有效性和精确性.

Abstract: It studies numerical simulation of two-dimensional hydrodynamic instability and the laser ablative interfaces instability of the inertial confinement fusion by applying the level-set-methods and the ENO method. Numerical examples are given, which demonstrate the efficiency of the present scheme for the numerical siumlation of interfaces instability.

Key words: inertial confiment fusion, laser ablative, Rayleigh-Taylor instability, level-set-method, ENO scheme
