Abstract
The aim of the present article is to clarify the nature of interaction between thermal and solutal buoyancy for flow over a horizontal, isot hermal, circular cylinder. In a range of values of the buoyancy ratio N (defined as the ratio of solutal to thermal Grashof numbers) an inte resting ''biplume'' solution has been obtained in which an upward ther mally driven flow coexists with a solutally driven downward flow. The problem has been studied for air-naphthalene (Lewis number Le = 3.57) and water-salt (Le = 100) binary systems.
