| Popis: | Direct 2‐D numerical simulation of the fluid instability of a shock‐accelerated thin gas layer shows flow patterns in agreement with experimental images. The Eulerian‐based hydrodynamics code features Adaptive Mesh Refinement that allows the code to follow the vorticity generation and the complex flow resulting from the measured initial perturbations. These experiments and simulations are the first to address in quantitative detail the evolution of the Richtmyer–Meshkov instability in a thin fluid layer, and to show how interfluid mixing and vorticity production depend sensitively on initial perturbations in the layer. |
