WebDiffusion occurs because random thermal motions are statistically more likely to move molecules out of a region of higher concentration than in the reverse direction, simply … WebReaction-diffusion equations describe the behaviour of a large range of chemical systems where diffusion of material competes with the production of that material by some form of chemical reaction. Many other kinds of systems are described by the same type of relation.

Blowup in Reaction-Diffusion Systems with Dissipation of Mass

Reaction–diffusion systems are mathematical models which correspond to several physical phenomena. The most common is the change in space and time of the concentration of one or more chemical substances: local chemical reactions in which the substances are transformed into each other, and diffusion … See more The simplest reaction–diffusion equation is in one spatial dimension in plane geometry, $${\displaystyle \partial _{t}u=D\partial _{x}^{2}u+R(u),}$$ is also referred to as … See more For a variety of systems, reaction–diffusion equations with more than two components have been proposed, e.g. the See more Well-controllable experiments in chemical reaction–diffusion systems have up to now been realized in three ways. First, gel reactors or filled capillary tubes may be used. Second, temperature pulses on catalytic surfaces have been investigated. Third, the … See more Two-component systems allow for a much larger range of possible phenomena than their one-component counterparts. An important idea that was first proposed by Alan Turing is that a state that is stable in the local system can become unstable in the presence of See more In recent times, reaction–diffusion systems have attracted much interest as a prototype model for pattern formation.
