[HTML][HTML] Numerical investigation of 3D effects on a 2D-dominated shocked mixing layer
A nominally two-dimensional interface, unstable to the Rayleigh-Taylor or Richtmyer-
Meshkov instability, will become three-dimensional at high Reynolds numbers due to the
growth of background noise and 3D effects like vortex stretching. This three-dimensionality
changes macroscopic features, such as the perturbation growth rate and mixing, as it
enhances turbulent dissipation. In this study, a 2D perturbation with small-scale, 3D
fluctuations is modeled using the hydrodynamics code Miranda. A Mach 1.95 shockwave …
