Review of the binary mixture droplet evaporation studies

Understanding the evaporation characteristics of sessile binary mixture droplets (BMDs) is crucial in various industries, such as surface coating, ink-jet printing, evaporators, fuel combustion, and medical diagnosis. The underlying physics of BMDs has not yet been fully explored despite numerous prior studies. This paper reviews the recent studies on evaporating BMD and examines various studied and unaddressed issues. First, we introduce measurement techniques to estimate time-varying mixture concentrations of BMDs during evaporation. Next, the theoretical models that have been developed to predict selective evaporation dynamics of BMDs are reviewed and summarized. Finally, this paper reviews the recent studies that have examined the three distinct stages of the contact line motion and internal flows of BMDs
