TL;DR: A novel method to set highly accurate initial conditions has been designed in the context of shock tube experiments for the Richtmyer-Meshkov instability study, and the visualizations of both heavy-light and light-heavy sinusoidal interfaces were carried out with laser sheet diagnostics.

TL;DR: In this paper, the authors investigated the nonlinear evolution of 2D single-mode Richtmyer-Meshkov instabilities through experiments in shock tube and numerical simulations, and compared experimental and numerical results, verify that using a higher Mach number for the incident shock wave (Misw) than in a previous study [C. Mariani, M. Vandenboomgaerde, G. Jourdan, D. Souffland, and L. Houas] drastically reduced the deleterious effects of the membrane remnants, explore the effect of a high initial

TL;DR: In this article, the Richtmyer-Meshkov instability (RMI) was studied in a cylindrical geometry with a converging shock wave, and the first results were presented for an incident planar shock wave of Mach number 1.15 propagating through an adequately elliptical gaseous interface.

TL;DR: In this paper, the cylindrical Richtmyer-Meshkov (RM) instability is studied in a shock tube and the growth rate of this instability does not saturate in the nonlinear regime as it does in the planar geometry.

TL;DR: In this paper, the authors used a gas lens to convert a planar shock wave into a cylindrical one through a perfect gas lens, which can be used to generate a circular transmitted shock wave.
