A finite volume model capable of predicting the influence of gas flow on the evaporation flux profile of sessile droplets during convective drying is presented. Evaporation flux distributions originating under a variety of conditions and at various stages in the drying process of water droplets in air are investigated and quantified. As an extension to already existing models this numerical simulation takes the advection of vapor in the flow field and the hereby arising concentration gradient shift along the droplet surface into account. This allows for a representation of not only the overall convective drying process, but particularly the resulting local evaporation at different stages and under different flow conditions. Finally, the influence of another droplet present in the vicinity is analyzed with special regard to surface flux distribution. Latter, and indices evaluated from it, is seen as an indicator for solids transport in the droplet and for deposit formation.
