The condensate liquid movement by applying bulk temperature gradient on the heat transfer surface in solutal Marangoni condensation was investigated, considering the application to the heat transfer devices. In solutal Marangoni condensation process, the removal of condensate on the heat transfer surface is important to keep good heat transfer. It may be useful for the heat transfer device in which the liquid movement occurs without external forces such as gravity, vapor shear force and so forth. As a result of the experiment using water - ethanol vapor mixture, the movement of the droplets from low temperature-side to high temperature-side could be observed on the heat transfer surface arranged horizontally. Furthermore, the relation between the velocity of drop movement and the gradient of surface tension was studied for different concentration.
