Numerical simulation of turbulent mixing by Rayleigh-Taylor instability
TL;DR: In this article, two-dimensional hydrodynamic codes are used to simulate the growth of perturbations at an interface between two fluids of different density due to Rayleigh-Taylor instability.
Journal ArticleDOI

TL;DR: In this paper, the authors investigated the turbulent Rayleigh-Taylor instability in the limit of strong mode-coupling using a variety of high-resolution, multimode, three dimensional numerical simulations (NS).
Journal ArticleDOI
Three-dimensional numerical simulation of turbulent mixing by Rayleigh-Taylor instability
TL;DR: In this paper, a three-dimensional simulation of the mixing of miscible fluids by Rayleigh-Taylor instability is described for density ratios, ρ 1/ρ2, in the range 1.5 to 20.
Journal ArticleDOI
An improved reconstruction method for compressible flows with low Mach number features
TL;DR: Numerical tests demonstrate that the new scheme captures shock waves well, significantly improves resolution of low Mach number features and greatly reduces high wave number dissipation in the case of homogeneous decaying turbulence and Richtmyer-Meshkov mixing.
