We have investigated the effects of a smooth transition layer at the contact discontinuity on the growth of the Richtmyer-Meshkov instability (RMI) by hydrodynamic numerical simulations, and we derived an empirical condition for the suppression of the instability. The transition layer has little influence on the RMI when the thickness L is narrower than the wavelength of an interface modulation λ. However, if the transition layer becomes broader than λ, the perturbed velocity associated with…

Inertial-confinement fusion with lasers

The quest for controlled fusion energy has been ongoing for over a half century. The demonstration of ignition and energy gain from thermonuclear fuels in the laboratory has been a major goal of

Instability of the interface of two gases accelerated by a shock wave

Results are presented of an experimental study of the stability of the interface of two gases traversed by ashockwave. It is found that the interface is unstable both in the case of shock wave

Numerical Investigation of the Stability of a Shock‐Accelerated Interface between Two Fluids

Recent experiments by Meshkov have demonstrated that a shock‐accelerated perturbed surface separating two gases of different densities is unstable for shocks traveling from the lighter gas to the
