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 …

Convection-driven porous media flows are common in industrial processes and in nature.
The multiscale and multiphase character of these systems and the inherent nonlinear flow …

Double-diffusive convection is a mixing process driven by the interaction of two fluid
components which diffuse at different rates. Leading expert Timour Radko presents the first …

We study the viscous-fingering instability in a radial Hele-Shaw cell in which the top
boundary has been replaced by a thin elastic sheet. The introduction of wall elasticity delays …

The buoyancy-driven instabilities triggered by neutralization reaction were studied
experimentally in a miscible two-layer system placed in a vertically oriented Hele-Shaw cell …

In partially miscible two-layer systems within a gravity field, buoyancy-driven convective
motions can appear when one phase dissolves with a finite solubility into the other one. We …

The buoyancy-driven chemoconvection induced by a neutralization reaction is theoretically
studied for a system consisting of nitric acid and sodium hydroxide aqueous solutions …

Dissolution of CO 2 into saline aquifers can lead to the development of buoyancy-driven
convection in the brine which enhances the efficiency of CO 2 transfer. We analyze here …

Upon contact between miscible solutions of reactants A and B along a horizontal interface in
the gravity field, various buoyancy-driven instabilities can develop when an A+ B→ C …

In a binary fluid mixture, the concentration gradient of a heavier molecular solute leads to a
diffusive flux of solvent and solute to achieve thermodynamic equilibrium. If the solute …
