Perturbation solution of the shape of a nonaxisymmetric sessile drop.
We develop an approximate analytical solution for the shape of a nonaxisymmetric sessile drop using regular perturbation methods and ignoring gravity. We assume that the pinned, contorted triple-line shape is known and is a small perturbation of the circular footprint of a spherical cap. We obtain an analytical solution using regular perturbation methods that we validate by comparing to the num...
متن کاملFootprint geometry and sessile drop resonance.
In this work, we examine experimentally the resonance of a sessile drop with a square footprint (square drop) on a flat plate. Two families of modal behaviors are reported. One family is identified with the modes of sessile drops with circular footprints (circular drop), denoted as "spherical modes." The other family is associated with Faraday waves on a square liquid bath (square Faraday waves...
متن کاملA Note on the Binomial Drop Polynomial of a Poset
Suppose (P,-<) is a poset of size n and n: P-~ P is a permutation. We say that n has a drop at x if n(x)~x. Let fie(k) denote the number of n having k drops, 0 <~ k < n, and define the drop polynomial A p(2) by Further, define the incomparability graph I(P) to have vertex set P and edges 0" whenever i and j are incomparable in P, i.e., neither i-<j nor j< i holds. In this note we give a short p...
متن کاملShape of a sessile drop on a flat surface covered with a liquid film.
Motivated by the development of lubricant-infused slippery surfaces, we study a sessile drop of a nonvolatile (ionic) liquid which is embedded in a slowly evaporating lubricant film (n-decane) on a horizontal, planar solid substrate. Using laser scanning confocal microscopy we imaged the evolution of the shape of the liquid/liquid and liquid/air interfaces, including the angles between them. Re...
متن کاملNonlinear oscillations of a sessile drop on a hydrophobic surface induced by ac electrowetting.
We examine the nature of ac electrowetting (EW)-driven axisymmetric oscillations of a sessile water drop on a dielectric substrate. In ac EW, small-amplitude oscillations of a drop differ from the Rayleigh linear modes of freely oscillating drops. In this paper, we demonstrate that changes in the time-averaged contact angle of the sessile drop attributed to the presence of an electric field and...
