Abstract The evaporation of a drop containing an involatile salt and surrounded by pure vapour is considered. The surface tension of the solution varies with the salt concentration and therefore surface tension gradients are set up when there is a temperature gradient in the vapour. In consequence the liquid and vapour phases are set in motion and the drop experiences a force which is usually in the opposite direction to the temperature gradient. The force is substantial in high pressure steam… CONTINUE READING
