WebJun 1, 1997 · Abstract In a liquid column thermocapillary convection arises under the action of an axial temperature gradient. The influence of a constant axial velocity of the column and its rotation about the longitudinal axis has been investigated. The effect of changing aspect ratio, Prandtl number and thermal expansion coefficient has also been determined.
