Initial spreading of low-viscosity drops on partially wetting surfaces.
Liquid drops start spreading directly after coming into contact with a partially wetting substrate. Although this phenomenon involves a three-phase contact line, the spreading motion is very fast. We study the initial spreading dynamics of low-viscosity drops using two complementary methods: molecular dynamics simulations and high-speed imaging. We access previously unexplored length and time s...
متن کاملRelaxation 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 کاملSpreading of blood drops over dry porous substrate: complete wetting case.
HYPOTHESIS The process of dried blood spot sampling involves simultaneous spreading and penetration of blood into a porous filter paper with subsequent evaporation and drying. Spreading of small drops of blood, which is a non-Newtonian liquid, over a dry porous layer is investigated from both theoretical and experimental points of view. EXPERIMENTS AND THEORY A system of two differential equa...
