A Refraction Method of Measurement of the Rate of Evaporation of a Liquid Droplet Under Conditions of Pinning of a Contact Line

详细

A laser refraction method of measurement of the rate of evaporation of a liquid droplet on a horizontal substrate under the conditions of pinning of a contact line is developed. Experimental values of the contact wetting angle in the evaporation process are obtained with the use of refraction images of the droplet. The time dependence of the volume of an evaporated droplet is established based on these values.
