Review of the binary mixture droplet evaporation studies

Abstract

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.

Theoretical and experimental study of heat and mass transfer, evaporation and ignition drops of monoatomic ethanol/butanol binary mixture in cold air

“…Вступ. При випаровуванні крапель бінарного розчину відоме поняття «вибіркового випаровування» [1], при якому більш летючий компонент випаровується швидше, оскільки його тиск насиченої пари біля поверхні краплівищий. В якості бінарних розчинів, як об'єктів таких досліджень, часто використовуються розчини води та спиртів (етанолу, метанолу, бутанолу) [2][3][4][5], різних спиртів (ізопропанолу та бутанолу) [6].…”

Inducing stratification of colloidal mixtures with a mixed binary solvent

“…69 The evaporation behavior of liquid mixtures is also under active exploration because of its practical relevance to real systems and technologies where materials involved are typically multicomponent. [70][71][72][73][74][75] Interestingly, Song et al showed that when the mixture of a volatile (methanol) and a much less volatile (1-butanol) component is evaporated, the two components develop opposite concentration gradients at the evaporation front, with 1-butanol enriched and methanol depleted near the interface. 76 It is interesting to explore if such inhomogeneity in solvent distribution that has developed during evaporation because of the contrasting volatilities of the mixed solvent components can be utilized to tune the distribution of colloidal particles in a drying film.…”

“…The evaporation rate for a droplet of a binary solution consisting of two different liquid components is not constant and changes in time, because each component evaporates at a different rate. This phenomenon is called "selective evaporation" [1]: the C i t a t i o n: Kopiyka O.K., Kalinchak V.V., Chernenko A.S.

“…In recent decades, when determining the concentrations of components during the droplet evaporation, changes in the geometry of a droplet lying on a certain surface were studied [1][2][3]. One of the characteristic parameters is the contact angle, the angle between the droplet-air boundary and the surface, which is governed by the surface tensions at the interfaces between the contacting phases.…”
