摘要: The open system consisting of a sessile drop, neutral gas, and substrate is analyzed by numerical methods. mode with constant contact angle considered. model takes into account evaporation from drop surface, free forced convection in buoyancy, Marangoni effect the liquid phase. It was established that every considered mechanical thermodynamical disturbance leads to surface oscillations, thus an air oscillates almost inevitably. displacement liquid-gas interface due oscillations terms its impact on accuracy measurement tension method.
