Applications of a high temperature sessile drop device

AlGaN/GaN MODFET Device for High Temperature Applications

The objective of this paper is to investigate the feasibility and explore the potential of GaN-based devices for high temperature applications. An analytical temperature model based on modified charge control model is developed for the proposed device. The major tasks of this paper include the establishment of the compact model including the thermal effects and the validation of the analytical ...

Footprint 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...

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...

Thermocapillary-driven motion of a sessile drop: effect of non-monotonic dependence of surface tension on temperature.

We study the thermocapillary-driven spreading of a droplet on a nonuniformly heated substrate for fluids associated with a non-monotonic dependence of the surface tension on temperature. We use lubrication theory to derive an evolution equation for the interface that accounts for capillarity and thermocapillarity. The contact line singularity is relieved by using a slip model and a Cox-Voinov r...
