Numerical Investigation of Richtmyer-meshkov Instability Using Front Tracking
نویسندگان
چکیده
Front tracking simulations of the Richtmyer-Meshkov instability produce signiicantly better agreement with experimentally measured growth rates than previously reported. Careful analysis of the early stages of the shock acceleration process show that nonlin-earity and compressibility play a critical role in the behaviour of the shocked interface and are responsible for the deviations from Richtmyer's impulsive model. The late time behaviour of the interface growth rate is compared to with a nonlinear potential ow model of Hecht, et al.

Viscous non-linear theory of Richtmyer-Meshkov Instability
We propose a quantitative prediction of the effect of viscosity on the weakly non-linear impulsive Richtmyer-Meshkov instability between two fluids of arbitrary densities and viscosities. This theory is based on an asymptotic analysis of the Navier-Stokes equations using singular perturbation techniques. The law obtained for the interface deformation does not agree with former theoretical predi...
متن کاملQuantitative theory of Richtmyer-Meshkov instability.
The acceleration of a material interface by a shock wave generates an interface instability known as the Richtmyer-Meshkov instability. Previous attempts to model the growth rate of the instability have produced values that are almost twice that of the experimental measurements. This article presents numerical simulations using front tracking that for the rst time are in quantitative agreement ...
متن کاملNon-linear dynamics of the Richtmyer-Meshkov instability in supernovae
We report analytical and numerical solutions describing the evolution of the coherent structure of bubbles and spikes in the Richtmyer-Meshkov instability in supernovae. It is shown that the dynamics of the flow is essentially non-local, and the nonlinear Richtmyer-Meshkov bubble flattens and decelerates.
متن کاملNonlinear evolution of the Richtmyer-Meshkov instability
We report analytical and numerical results describing the dynamics of the two-dimensional coherent structure of bubbles and spikes in the Richtmyer-Meshkov instability for fluids with a finite density ratio. The theory accounts for the non-local properties of the interface evolution, and the simulations treat the interface as a discontinuity. Good agreement between the analytical and numerical ...
متن کاملSpherical Richtmyer-Meshkov instability for axisymmetric flow
Front tracking has proved to be an accurate and efficient algorithm in the sense that tracking the interface can reduce the error significantly [9,10]. By applying this algorithm, we conduct numerical simulations of Richtmyer–Meshkov (RM) instabilities in spherical geometry for axisymmetric flow. We demonstrate scaling invariance with respect to shock Mach number for fluid mixing statistics, su...
