Numerical Investigation of Richtmyer-meshkov Instability Using Front Tracking
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 Richt...
متن کاملNumerical investigation of Richtmyer - Meshkov instability driven by cylindrical shocks ∗
In this paper, a numerical method with high order accuracy and high resolution was developed to simulate the Richtmyer-Meshkov(RM) instability driven by cylindrical shock waves. Compressible Euler equations in cylindrical coordinate were adopted for the cylindrical geometry and a third order accurate group control scheme was adopted to discretize the equations. Moreover, an adaptive grid techni...
متن کاملHypervelocity Richtmyer–Meshkov instability
The Richtmyer–Meshkov instability is numerically investigated for strong shocks, i.e., for hypervelocity cases. To model the interaction of the flow with non-equilibrium chemical effects typical of high-enthalpy flows, the Lighthill–Freeman ideal dissociating gas model is employed. Richtmyer’s linear theory and the impulse model are extended to include equilibrium dissociation chemistry. Numeri...
متن کاملThe Richtmyer-meshkov Instability
■ Abstract The Richtmyer-Meshkov instability arises when a shock wave interacts with an interface separating two different fluids. It combines compressible phenomena, such as shock interaction and refraction, with hydrodynamic instability, including nonlinear growth and subsequent transition to turbulence, across a wide range of Mach numbers. This review focuses on the basic physical processes ...
متن کاملNumerical simulations of the Richtmyer-Meshkov instability with reshock
Two-dimensional simulations of the Richtmyer-Meshkov instability with re-shock are carried out based on the single-mode Mach 1.21 air/SF6 shock tube experiments of Collins and Jacobs. A second-order accurate MUSCL-Hancock scheme and several high-order WENO schemes are used for shock capturing along with a gamma-based model for interface capturing to allow for the stable and accurate representat...
