Smart baffle placement for chaotic mixing
It is well known that fluid mixing can often be improved by the introduction of âbafflesâ into the flow â the problem of baffle placement is examined here for chaotic fluid mixing of a highly viscous fluid. A simple model for a planetary mixer, with one stirring element, is modified by the introduction of one or more stationary baffles. Regular regions of poor mixing in the unbaffled flow are shown to be significantly reduced in size if the location of the baffles is chosen so that the flow necessarily generates âtopological chaosâ. By contrast, the positioning of baffles in superficially similar ways that do not generate such âtopological chaosâ fails to provide a similar improvement.Michael J. Clifford, Stephen M. Co
