The Evaporation of Sessile Droplets. 1. Theoretical Factors for a Two- Component System

Abstract

The fundamental principles that need to be included in any analysis of the evaporation of a sessile droplet of a two-component solution are provided in this report. The equations needed to calculate the behavior of a sessile droplet of a two-component solution are integrated into a model. A computer program is provided, and a calculation with the model is compared with data for a sessile water droplet on an aluminum surface. Keywords: Hildebrand parameter; Activity coefficients; Partial vapor pressures; Solutions; Water; Surface chemistry; Sessile droplet; Evaporation. (jhd)
