Relaxation of nonspherical sessile drops towards equilibrium.
We present a theoretical study related to a recent experiment on the coalescence of sessile drops. The study deals with the kinetics of relaxation towards equilibrium, under the action of surface tension, of a spheroidal drop on a flat surface. For such a nonspherical drop under partial wetting conditions, the dynamic contact angle varies along the contact line. We propose a new nonlocal approa...
متن کاملQuasistatic relaxation of arbitrarily shaped sessile drops.
We study a spontaneous relaxation dynamics of arbitrarily shaped liquid drops on solid surfaces in the partial wetting regime. It is assumed that the energy dissipated near the contact line is much larger than that in the bulk of the fluid. We have shown rigorously in the case of quasi-static relaxation using the standard mechanical description of dissipative system dynamics that the introducti...
متن کاملOn Modeling Evaporation of Sessile Drops
Evaporating drops and thin films have numerous applications, from nanometric photoresist films in semiconductor applications to small sessile drops used for analysis of DNA microarrays [1]. Evaporating sessile drops are particularly interesting due to nonuniform drop thickness and the presence of contact lines (separating liquid, gas and solid phase). These factors may lead to nonuniform evapor...
متن کاملFour - phase merging in sessile compound drops
We consider the statics of compound droplets made of two immiscible fluids on a rigid substrate, in the limit when gravity is dominated by capillarity. In particular, we show that the merging of four phases along a single contact line is a persistent and robust phenomenon from a mechanical and thermodynamic perspective; it can and does occur for a range of interfacial energies and droplet volum...
متن کاملMechanical and Associated Discharge Behaviour of Sessile Water Drops
To assist efforts to understand the phenomena involved in the generation of tonal emissions from wet high voltage transmission lines, water drop geometries on various surfaces have been studied with and without exposure to electric fields. In a small-size arrangement, discharges from individual water drops were observed in terms of current and UV light emission; geometry changes were recorded b...
