Interfacial fluid mixing driven by an external acceleration or a shock wave are common
phenomena known as Rayleigh–Taylor instability and Richtmyer–Meshkov instability …

When a planar shock hits a corrugated interface between two fluids, the Richtmyer–Meshkov
instability (RMI) occurs. Vortices are generated in bulk behind the transmitted and reflected …

The nonlinear interaction between bulk point vortices and a vortex sheet with initially
nonuniform velocity shear is investigated theoretically and numerically by use of the vortex …

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 …

In this paper, we study the long-time evolutions of the single-and multi-mode Rayleigh–
Taylor instability with surface tension in two dimensions by using the vortex sheet model …

In this paper, we study long-time evolutions of the Kelvin–Helmholtz instability with surface
tension and density jump by using the vortex sheet model. Applying a spectrally accurate …

The time development of an interface separating two immiscible fluids of different densities
in heterogeneous two-dimensional porous media is studied. The governing equations are …

Radial propellant injection in the annular combustion chamber of a rotating detonation
engine (RDE), done in a manner to promote maximum size scale of vortices, has proven to …

The single-mode Rayleigh-Taylor instability (smRTI) is well defined, poorly understood, and
applicable to many fluid flows directly and through its relationship to multi-mode Rayleigh …

Inertia-dominated hydrodynamic instabilities at material interfaces are ubiquitous
phenomena observed in nature and man-made applications, spanning core collapse …
