| Abstract: | Steady state flow field around ablation front is solved and taken as a basic flow in the simulation of ablative Rayleigh-Taylor instability with a high-order WENO scheme.Linear growth rate simulated agrees with Lindl formula and linear stability analysis.It indicates validity and accuracy of the method.The method shows good ability in capturing interface deformation. |
