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 is useful for comparisons with experimental and computational investigations of this phenomenon in a cylindrical tank with two rotating cylinders.
