Droplet mobilization in actuated deformable tubes
Sthavishtha R. Bhopalam, Ruben Juanes, Hector Gomez
We study the mobilization of an oil droplet in a deformable, actuated constricted tube subjected to two different actuation mechanisms: hydrodynamic actuation (oscillatory body for…

Simulating fluid-fluid displacement in a soft capillary tube: How compliance delays interfacial instability and bubble pinch-off
Sthavishtha R. Bhopalam, Ruben Juanes, Hector Gomez
The displacement of a more viscous fluid by a less viscous immiscible fluid in confined geometries is a fundamental problem in multiphase flows. Recent experiments have shown that…
