A model for Marangoni flows that we observed on plane free surfaces of thin layers of aqueous fatty alcohol solutions is developed by considering evaporation-condensation of alcohol. The velocities of surface-tension-driven flows caused by gradients in temperature and in concentration are evaluated
## Abstract The surface tension drivenβflow in BaB~2~O~4~ (BBO) meltβsolution is visualized by differential interference microscope coupled with Schlieren technique, and the streamline of the steady thermocapillary convection is found to be in form of an axially symmetric pattern. Based on the obse
