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…
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…
Preferential Condensation of water droplets using hybrid hydrophobic-hydrophilic surfaces
Adam T. Paxson, Kripa K. Varanasi, Tao Deng +2
We present a hybrid microtextured surface with heterogeneous hydrophilic-hydrophobic regions for condensing water vapor while maintaining anti-wetting behavior. Fluid dynamics vide…
