INTERACTION OF TURING AND FLOW-INDUCED CHEMICAL INSTABILITIES

The interaction between the Turing instability and the instability ind uced by a differential flow is studied in the Selkov model. Both insta bilities give rise to the formation of spatial patterns, and for a ran ge of parameter values, these patterns can compete. The effect of anis otropic diffusion on the pattern formation process is investigated. St ripes with different orientations that travel with time and the suppre ssion of patterns due to a competition of both instabilities are obser ved.
