Experimental study of Richtmyer-Meshkov instability in a cylindrical converging shock tube

Richtmyer-Meshkov Instability and Gas-particle Interaction of Contoured Shock-tube Flows: a Numerical Study

In this paper, computational fluid dynamics (CFD) is utilized to characterize a prototype biolistic delivery system, the biomedical device based on the contoured-shock-tube design (CST), with the aim at investigating shocks induced flow instabilities within the contoured shock tube. The shock/interface interactions, the growth of perturbation at an interface between two fluids of different dens...

Linear simulations of the cylindrical Richtmyer-Meshkov instability in magnetohydrodynamics

Experimental Studies of Richtmyer–Meshkov Instability∗

Two novel experiments are reported which improve upon previous experimental studies of Richtmyer-Meshkov instability in that very well controlled initial interfaces are obtained. The first is an incompressible experiment in which an impulsive acceleration is given to a system of two liquids by bouncing it off of a fixed spring. The second is a shock tube experiment in which a well controlled fl...

Hypervelocity 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...

Numerical 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...
