Abstract
Experimental studies of evaporation of water droplets lying on hydrophobic surfaces were carried out using non-contact measurement methods. The behavior of a contact angle and contact spot size was investigated using high-speed micro photography. The dynamics of the change in an average temperature of the surface of evaporating droplets was studied by the method of infrared thermography. For a theoretical study of the evaporation of liquid droplets, the previously developed emission-diffusion model, which takes into account the influence of the contact angle on the droplet evaporation rate, was used. The results of computations and experiments were compared and satisfactory agreement was obtained.
