Dispersive element reaction-induced

Taylor-Flow Microreactors Taylor-flow microreactors contain a dispersing mixing element for gas and liquid streams, typically of Tand Y shapes, followed by a reaction channel for the segmented gas-liquid flow, often of quite extended length, as the Taylor flow is dominant in typical flow-pattern maps [230,248-250]. In general, all Taylor-flow microreactors can induce other flow patterns as well as the ones mentioned above. 

In the context of plankton dynamics an interesting development that has some common ideas with the KiSS approach but introduces a new and important element is described in Martin (2000). The idea is that dispersion of a patch is not only controlled by eddy diffusivity, but also by the geometric characteristics of the mean flow. It turns out that if an incompressible fluid flow induces dispersion in one direction it necessarily produces convergence in another, to conserve the fluid volume. This was already exploited in Sect. 2.7.1, and includes the ingredient of advection, in addition to the reaction-diffusion processes which are the subject of this Chapter. Nevertheless, since this case can be analyzed easily and extends the KiSS model, we consider it here.
