Abstract

In order to address the issue of gold mixing caused by the Kelvin-Helmholtz instability(KHI)in the double-cone ignition(DCI)scheme,we investigate the growth rate of the KHI at the bi-interface of the DCI scheme after applying a coating.This is done by solving the hydrodynamic equations for an ideal incompressible fluid using linear theory.Ultimately,it is discovered that applying a coating with a thickness slightly above h=0.5(λ+10 μm)and a density somewhat lower than that of the target layer can effectively reduce the growth rate of interfacial KHI.This work provides theoretical references for studying the bi-interface KHI in the DCI scheme.
