Regimes of thermocapillary migration of droplets under partial wetting conditions

JM Gomba, GM Homsy - Journal of Fluid Mechanics, 2010 - cambridge.org
We study the thermocapillary migration of two-dimensional droplets of partially wetting
liquids on a non-uniform heated substrate. An equation for the thickness profile of the droplet …

Thermocapillary migration of droplets under molecular and gravitational forces

JR Mac Intyre, JM Gomba, CA Perazzo… - Journal of Fluid …, 2018 - cambridge.org
We study the thermocapillary migration of two-dimensional droplets of partially wetting
liquids on a non-uniformly heated surface. The effect of a non-zero contact angle is imposed …

Contact line motion in axial thermocapillary outward flow

Linear stability analysis of a droplet under an axisymmetric thermal gradient

RA Mansilla, CA Perazzo, JM Gomba - Physics of Fluids, 2024 - pubs.aip.org
We study the linear stability of a droplet placed at the center of a horizontal disk under the
effect of surface stress promoted by an axisymmetric thermal gradient. Since the fluid volume …

Stability study of a constant-volume thin film flow

JM Gomba, J Diez, R Gratton, AG González… - Physical Review E …, 2007 - APS
We study the stability of a constant volume of fluid spreading down an incline. In contrast to
the commonly considered flow characterized by constant fluid flux, in the present problem …

Closed-form expression for the profile of partially wetting two-dimensional droplets under gravity

Analytical solutions for the shape of both hanging and sitting droplets under the effects of
gravity and surface tension are presented. The modeling also includes the action of …

Thin-film flows with moving contact lines: An approach to reducing computing time

JM Gomba - Physical Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
A numerical method to reduce the computing times of thin-film flows with moving contact
lines is presented. The flows of a film and a droplet are calculated in a frame that moves with …

Analytical solutions for the profile of two-dimensional droplets with finite-length precursor films
