By modifying a physical property of a solution like its density or viscosity, chemical reactions
can modify and even trigger convective flows. These flows in turn affect the spatiotemporal …

The scalings of the Rayleigh-Taylor instability are studied numerically for porous media
flows when the denser fluid lying on top of the less dense one is also much more viscous …

Abstract Non-isothermal Rayleigh-Taylor Instability (RTI) has been investigated for
incompressible, Newtonian, immiscible flows. Thermal gradients were triggered by imposing …

We analyze the asymptotic stability of the quasi-linearly stratified densities in the 2D inviscid
incompressible porous medium equation on R 2 with respect to the buoyancy frequency N …

We report experiments of fingering asymmetry in Rayleigh-Taylor (RT) mixing at an
extremely large viscosity ratio (M≈ 5× 10 5) and Rayleigh numbers [Ra∼ 10 5–(3× 10 6)] …

Chemohydrodynamic patterns due to the interplay of buoyancy-driven instabilities and
reaction–diffusion patterns are studied experimentally in a vertical quasi-two-dimensional …

We studied the influence of the diffusion contrast between species on the dynamics of
Rayleigh‐Bénard (RB) convection in porous media. The onset time of buoyancy‐driven …

The interface between two miscible solutions in porous media and Hele-Shaw cells (two
glass plates separated by a thin gap) in a gravity field can destabilise due to buoyancy …

We prove the quantitative asymptotic stability of the quasi-linearly stratified densities in the
2D inviscid incompressible porous medium equation on $\bbR^ 2$. The target density is the …

The effect of different diffusivities on the evolution of buoyancy-driven instability in a reactive-
diffusion system is analyzed. For an instantaneous A+ B→ C chemical reaction in a Hele …
