The deposition of particles on a surface by an evaporating sessile droplet is important for phenomena as diverse as printing, thin-film deposition, and self-assembly. The shape of the final deposit depends on the flows within the droplet during evaporation. These flows are typically determined at the onset of the process by the intrinsic physical, chemical, and geometrical properties of the dro...

The Sound attenuation and dispersion in saturated gas-vapor-droplet mixture in the presence of evaporation has been investigated theoretically. The theory is based on an extension of the work of Davidson (1975) to accommodate the effects of nonlinear particle relaxation processes of mass, momentum and energy transfer on sound attenuation and dispersion. The results indicate the existence of a s...

Despite recent research on blends of biodiesel with higher alcohols in Diesel engines, no information their behaviour as single droplets is available. This work presents experimental data the droplet evaporation 1-propanol and 1-pentanol compares them to results numerical models evaporation. The phase equilibrium non-ideal mixture alcohol was modelled using activity coefficients calculated from...

The evaporation of multiple sessile droplets is both scientifically interesting and practically important, occurring in many natural industrial applications. Although there are simple analytic expressions to predict rates single droplets, no such frameworks for general configurations arbitrary size, contact angle or spacing. However, a recent theoretical contribution by Masoud, Howell & Sto...

Wide used technique of patterning surfaces with solid particles utilizes the evaporation of colloidal droplets from a substrate. In particular, evaporation of liquid samples is a key problem in the development of microarray technology (including labs-on-a chip), especially in the case of open reactors [1]. A plenty of works are devoted to the evaporation of the sessile droplets [2–5]. One assum...

In this paper we study the behavior of an inkjet-printed droplet of a solute dissolved in a solvent on a solid horizontal surface by numerical simulation. An extended model for drying of a droplet and the final distribution of the solute on an impermeable substrate is proposed. The model extends the work by Deegan, Fischer and Kuerten by taking into account convection, diffusion and adsorption ...

In this work, we study metal droplets on a semiconductor surface that are the initial stage for both droplet epitaxy and local droplet etching. The distributions of droplet geometrical parameters such as height, radius and volume help to understand the droplet formation that strongly influences subsequent nanohole etching. To investigate the etching and intermixing processes, we offer a new met...

Evaporation is ubiquitous in nature. This process influences the climate, the formation of clouds, transpiration in plants, the survival of arctic organisms, the efficiency of car engines, the structure of dried materials and many other phenomena. Recent experiments discovered two novel mechanisms accompanying evaporation: temperature discontinuity at the liquid–vapour interface during evaporat...

In this study, evaporation of sessile water droplets on hot micro-structured superhydrophobic surfaces is experimentally and theoretically investigated. Water 4 µL are placed micro-pillared silicon substrates with the substrate temperature heated up to 120°C. A comprehensive thermal circuit model developed analyze effects roughness droplet evaporation. For first time, two components heat mass t...

By using a lattice Boltzmann method for simulating droplet evaporation (R. Ledesma-Aguilar et al., Soft Matter, 2014, 10, 8267) we investigate the evaporation of single and multiple droplets. The numerical results show a good agreement with experiments of the evaporation of alcohol droplets in water with regards to the typical timescales and the convection fields. We also show the slow-down in ...
