Data for droplet mobilization in actuated deformable tubes

<p><strong>Overview</strong>: This dataset includes simulation data for the motion of an oil droplet by water in a deformable, actuated constricted capillary tube. This is a fluid-structure interaction (FSI) problem involving two immiscible fluids. Our computational model employs a phase-field model for the fluids’ governing equations and a nonlinear hyperelastic model for the solid. Our focus is on micro-scale problems, where the interplay between capillary forces, viscous forces, elastic forces and actuation techniques controls the mobilization efficacy of the droplet in the tube.</p>

<p><strong>Context and Objective</strong>: The primary objective of this dataset is to elucidate the effects of two actuation techniques: hydrodynamic actuation and wall actuation on droplet mobilization in the capillary tube. Our simulations can help us better understand the potential of actuation techniques in many applications, such as enhanced oil recovery processes, drug-delivery systems, soft robotics and surface-acoustic-wave (SAW) forcing.</p>

<p><strong>Data Collection</strong>: The data in this repository were collected from axisymmetric numerical simulations of a multi-component FSI model. Detailed information about our model and numerical formulation can be found in [1].</p>
