Just a few decades ago, chemical oscillations were thought to be exotic reactions of only
theoretical interest. Now known to govern an array of physical and biological processes …

Chemical reactions with nonlinear kinetic behavior can give rise to a remarkable set of
spatiotemporal phenomena. These include periodic and chaotic changes in concentration …

If we had to formulate in one sentence what this book is about, it might be “How partial
differential equations can help to understand heat explosion, tumor growth or evolution of …

Figure 1 shows the front position versus time for one experiment. The initial burst of heat
causes rapid propagation, but the front reaches a steady velocityafter a few minutes. Visual …

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

The influence of chemical reactions on the hydrodynamical fingering instability is analyzed
for miscible systems in porous media. Using a realistic reaction scheme, it is shown that the …

The problem of viscous fingering is studied in the presence of simultaneous chemical
reactions. The flow is governed by the usual Darcy equations, with a concentration …

Frontal polymerization is a process in which a spatially localized reaction zone propagates
into a monomer, converting it into a polymer. In the simplest case of free-radical …

Experimental studies were performed on the buoyancy-driven instability of an autocatalytic
reaction front in a quasi-2D cell. The unstable density stratification at an ascending front …

Observations of steady nonaxisymmetric chemical wave fronts are reported for
upwardpropagation in iodate-arsenous acid solutions within vertical capillary tubes. These …
