A previously developed model for mono-component droplet evaporation is revisited using new mathematical tools its analysis. The analysis based on steady-state mass, momentum, and energy balance equations the vapor air mixture surrounding a droplet. obtained solution to these was assumption that parameter ε (proportional squared ratio of diffusion coefficient radius) equal zero. presented in pap...

Droplet motion on solid substrates has been widely studied not only because of its importance in fundamental research but also because of its promising potentials in droplet-based devices developed for various applications in chemistry, biology, and industry. In this paper, we investigate the motion of an evaporating droplet in one-component fluids on a solid substrate with a wettability gradie...

Using the dynamic van der Waals theory [Phys. Rev. E 75, 036304 (2007)], we numerically investigate the hydrodynamics of Leidenfrost droplets under gravity in two dimensions. Some recent theoretical predictions and experimental observations are confirmed in our simulations. A Leidenfrost droplet larger than a critical size is shown to be unstable and break up into smaller droplets due to the Ra...
