We present an approximate analytical dispersion relationship for elastic–plastic acceleration-
driven instability growth. In this model, the accelerated solid behaves like a viscoplastic after …

The unique properties of magnetic fluids are exploited to create a static interface between
two fluids in the context of studying Rayleigh-Taylor (RT) driven mixing. Paramagnetic fluids …

The onset of instability in the presence of an oscillatory axial flow between concentric
rotating cylinders to both axisymmetric and nonaxisymmetric disturbances is investigated on …

A lattice Boltzmann model for multicomponent fluid flows is used to simulate the two-
dimensional Rayleigh-Taylor instability. The dynamical processes of the instability, varying …

The onset of instability in temporally modulated Taylor-Couette flow is considered. Critical
Reynolds numbers have been found by computing Floquet exponents. We find that …

A non-inertial (zero Taylor number) viscoelastic instability is discovered for Taylor–Couette
flow of dilute polymer solutions. A linear stability analysis of the inertialess flow of an Oldroyd …

In this paper, the three-dimensional (3D) Rayleigh-Taylor instability (RTI) with low Atwood
number (A t= 0.15) in a long square duct (12 W× W× W) is studied by using a multiple …

In this paper, we develop a fully anisotropic, nonlinear, thermodynamically consistent model
for single crystals under high rates of loading with thermodynamically consistent decoupling …

Abstract The Portevin–Le Châtelier (PLC) instability is commonly observed in Al–Mg alloys
and is manifested in serrated flow within the stress–strain response. We investigate the …

Direct numerical simulations of two-dimensional (2D) and three-dimensional (3D), single-
mode and multi-mode, incompressible immiscible Rayleigh–Taylor (RT) instabilities are …
