Chemical reactions can interplay with hydrodynamic flows to generate various complex
phenomena. Because of their relevance in many research areas, chemically-induced …

In this Letter, we study the interaction between a self-sustaining exothermic reaction front
propagating in a direction perpendicular to that of gravity and the buoyancy-driven …

Self-sustained reaction fronts in a disordered medium subject to an external flow display self-
affine roughening, pinning, and depinning transitions. We measure spatial and temporal …

When traveling in thin solution layers, autocatalytic chemical fronts may be deformed and
accelerated by convective currents that develop because of density and surface tension …

We analyze experimentally chemical wave propagation in the disordered flow field of a
porous medium. The reaction fronts travel at a constant velocity that drastically depends on …

A reactive interface in the form of an autocatalytic reaction front propagating in a bulk phase
can generate a dynamic contact line upon reaching the free surface when a surface tension …

A reaction–diffusion–convection (RDC) model is introduced to analyze convective dynamics
around horizontally traveling fronts due to combined buoyancy-and surface tension-driven …

Gradients of concentration and temperature across exothermic chemical fronts propagating
in free-surface solution layers can initiate Marangoni-driven convection. We investigate here …

We study theoretically buoyant displacement flows of two generalized Newtonian fluids in a
two-dimensional (2-D) channel with wall slip. We assume that a pseudo-interface separates …

The proposed method allows the detection and the measurement, in the sense of metrology,
of smooth elongated curvilinear shapes. Such measurements are required in many fields of …
