Evaporation From Single Droplets Impinging on Heated Surfaces

Thermal behaviour of liquid droplets on a heated solid surface was studied experimentally using metallic/nonmetallic solids of different characteristics and variety of liquids, from distilled water through pure organic solvents and binary mixtures to solutions, suspensions and emulsions. Nearly spherical particles were obtained from solutions and suspensions. Kraft black liquor was used as a model complex suspension with organic and inorganic components. Evaporation rates were measured for single droplets.
