[HTML][HTML] Vortex-sheet modeling of hydrodynamic instabilities produced by an oblique shock interacting with a perturbed interface in the HED regime

We consider hydrodynamic instabilities produced by the interaction of an oblique shock with
a perturbed material interface under high-energy-density (HED) conditions. During this
interaction, a baroclinic torque is generated along the interface due to the misalignment
between the density and pressure gradients, thus leading to perturbation growth. Our
objective is to understand the competition between the impulsive acceleration due to the
normal component of the shock velocity, which drives the Richtmyer–Meshkov instability …
