高阶FD-WENO格式在数值求解Rayleigh-Taylor不稳定性问题中的应用

High Order FD-WENO Schemes for Rayleigh-Taylor Instability Problems

用高阶加权本质上无振荡有限差分格式(FD-WENO),求解重力作用下高密度比二维流体界面Rayleigh-Taylor不稳定性问题及激光烧蚀Rayleigh-Taylor不稳定性问题,均获得较为理想的数值结果.

High order weighted essentially non-oscillatory finite difference schemes （FD-WENO） are applied successfully to numerical simulation of gravity-driven high density ratio Rayleigh-Taylor instability problems and laser ablative Rayleigh-Taylor instability problems in two dimensions. It provides important references to numerical study of inertial confinement fusion（ICF） as well as to other high-tech fields. High order FD-WENO schemes are applicable to numerical simulation of ICF inplosion.
