Abstract

Steady circulatory motions at the surface of tap-water flowing in an open channel and past a hemispherical air bubble on a channel wall are described and explained by the presence of a film of surface-active material. Boundary conditions for the liquid phase are derived by assuming that the surface film is insoluble and incompressible. Good agreement is obtained between the theoretical and measured velocity fields in the open-channel flow.
