Rayleigh taylor waves
WebA new approach to scaling blast wave instabilities is developed. When applied to the Rayleigh-Taylor case, unique scaling laws for explosion energy and density are derived. Connections with earlier scaling theory and turbulence are established. The validity of applying these scaling laws in the laboratory is demonstrated. WebThe growth can persist long after the rarefaction wave has passed, leading to significant enhancement of mixing. This rarefaction-driven Rayleigh-Taylor instability is studied numerically and compared with the analogous Richtmyer-Meshkov instability. Key words. Instability; Rarefaction wave
