The flow driven by buoyancy and diffusocapillary forces in a two-dimensional, low-aspect-ratio cavity is investigated theoretically. For creeping motions of a highly diffusive liquid, the flow field is solved analytically. It is found that, depending on the relative importance of buoyancy to diffusocapillarity, the flow may exhibit a single-cellular or a double-cellular motion. The corresponding flow patterns are calculated and the conditions for the transition of flow structures are determined.
