Chaotic advection by two-dimensional Stokes flow in a circle (English)
0 references
The Stokes flow due to a rotlet in a circle is determined. The solution shows that for a certain position of the rotlet, the flow has a second stagnation point symmetrically placed inside the circle. Thus, a ``blinking rotlet'' model can be constructed in which the rotlet that is ``off'' does not disturb the flow. This model seems preferable to the ``blinking vortex'' flow when discussing chaotic advection by a Stokes flow, and is useful for comparisons with experimental and computational investigations of this phenomenon in a cylindrical tank with two rotating cylinders.
