The nonlinear dynamics of the interface between media possessing differentdensities and symmetries

A time-saving method is proposed for the study of a nonlinear vortexless st age of a Rayleigh-Taylor (RT) instability development at the free surface o f a heavy liquid or a Richtmyer-Meshkov (RM) instability at the interface b etween continuous media possessing different densities and symmetries. The efficacy of the proposed method is demonstrated by the results of a special numerical experiment. It is shown that instability development at the soli d-plasma interface gives rise to stresses in the solid. (C) 2001 MAIK "Nauk a/Interperiodica".
