Preventing mass loss in the standard level set method: New insights from variational analyses
Kaustubh Khedkar, Amirreza Charchi Mamaghani, Pieter Ghysels +2
For decades, the computational multiphase flow community has grappled with mass loss in the level set method. Numerous solutions have been proposed, from fixing the reinitializatio…
Directional self-propelled transport of coalesced droplets on a superhydrophilic cylindrical wire
Leyun Feng, Youhua Jiang, Christian Machado +3
Droplets coalescing on flat surfaces tend to end up with the smaller droplet migrating into the larger one. We report a counter-intuitive droplet coalescence pattern on a superhydr…
Self-sustained oscillations in whiskers without vortex shedding
Shayan Heydari, Mitra J. Z. Hartmann, Neelesh A. Patankar +1
Sensing the flow of water or air disturbance is critical for the survival of many animals: flow information helps them localize food, mates, and prey and to escape predators. Acros…
Peristaltic regimes in esophageal transport
Guy Elisha, Shashank Acharya, Sourav Halder +5
A FLIP device gives cross-sectional area along the length of the esophagus and one pressure measurement, both as a function of time. Deducing mechanical properties of the esophagus…
A Fully Resolved Multiphysics Model of Gastric Peristalsis and Bolus Emptying in the Upper Gastrointestinal Tract
Shashank Acharya, Sourav Halder, Wenjun Kou +3
Over the past few decades, in silico modeling of organ systems has significantly furthered our understanding of their physiology and biomechanical function. In this work, we presen…
Boiling transitions during droplet contact on superheated nano/micro-structured surfaces
Navid Saneie, Varun Kulkarni, Kamel Fezzaa +2
Manipulating surface topography is one of the most promising strategies for increasing the efficiency of numerous industrial processes involving droplet contact with superheated su…
