摘要We report the formation of jet-like long spike in the nonlinear evolution of the ablative Rayleigh–Taylor instability (ARTI) experiments by numerical simulations. A preheating model κ(T)=κSH[1+f(T)], where κSH is the Spitzer–Härm (SH) electron conductivity and f(T) interprets the preheating tongue effect in the cold plasma ahead of the ablative front [Phys. Rev. E 65 (2002) 57401], is introduced in simulations. The simulation results of the nonlinear evolution of the ARTI are in general agreement with the experiment results. It is found that two factors, i.e., the suppressing of ablative Kelvin–Helmholtz instability (AKHI) and the heat flow cone in the spike tips, contribute to the formation of jet-like long spike in the nonlinear evolution of the ARTI.
