Free convection in a drop at liquid evaporation

Аннотация

This paper is devoted to the study of convection inside a droplet and its effect on heat transfer. A drop of water and a water-salt solution of the LiBr salt was located on a horizontal cylindrical surface of copper. The surface temperature was 53 °C. The novelty of the work is that the influence of free convection in gas and liquid is investigated experimentally. The analysis of experimental data has shown that in the initial period of water drop evaporation, the predominant role in the heat exchange is played by the thermal Marangoni convection.
