Sensitivity of cellular Stokes flow to geometry
Résumé
We present some experiments and calculations that illustrate the establishment of a cellular Stokes flow between two parallel plates. The structure of this flow is composed of successive closed eddies. The study of the influence of an additional plate mounted midway between the channel walls shows the sensitivity of these eddies to the variation of the geometry. We suggest that this flow might be introduced in the specialized teaching of fluid mechanics, to show examples of transfer by cellular motion.
