Aerophilic Debubbling
Bert J. C. Vandereydt, Saurabh Nath, Kripa K. Varanasi
In this letter, we characterize quantitatively the complex phenomenon of debubbling via aerophilic membranes by examining local interactions at the scale of single bubbles. We iden…
Self-Propulsion of Boiling Droplets on Thin Heated Oil Films
Victor Julio Leon, Kripa K. Varanasi
We report on the self-propulsion of boiling droplets which, despite their contact with viscous, immiscible oil films, attain high velocities comparable to those of levitating Leide…
Sticking around: an up-close look at drop adhesion
Adam T. Paxson, Kripa K. Varanasi
We present a fluid dynamics video showing the adhesion of a drop to a superhydrophobic surface. We use environmental scanning electron microscopy to observe depinning events at the…
Instabilities by ionic bombardment
Seyed Reza Mahmoudi, Sushant Anand, Kazimierz Adamiak +2
This fluid dynamics video is an entry for the Gallery of Fluid Motion of the 66th Annual Meeting of the APS-DFD. This work reveals new types of interfacial instabilities that occur…
Hovering UFO Droplets
Sushant Anand, Adam Paxson, Rajeev Dhiman +2
This fluid dynamics video is an entry for the Gallery of Fluid Motion of the 65th Annual Meeting of the APS-DFD. This video shows behavior of condensing droplets on a lubricant imp…
Deceleration Driven Wetting Transition During "Gentle" Drop Deposition
Hyuk-Min Kwon, Adam T. Paxson, Kripa K. Varanasi +1
We present high speed video of Cassie-Baxter to Wenzel drop transition during gentle deposition of droplets where the modest amount of energy is channeled via rapid deceleration in…
