Non-coalescence and in-plane momentum generation in sessile droplet clusters
Gopal Chandra Pal, Cheuk Wing Edmond Lam, Chander Shekhar Sharma
Intuitively, droplets in proximity merge when brought into contact. However, under certain conditions, they may not coalesce due to the entrapment of an interstitial gas film. Non-…

Pinning mediated coalescence-induced lateral droplet motion on nanotextured superhydrophobic surface
Raushan Kumar, Gopal Chandra Pal, Chander Shekhar Sharma
Droplets coalescing on a superhydrophobic surface exhibit coalescence-induced droplet jumping. However, water vapor condensing on a superhydrophobic surface can result in simultane…

Condensate droplet roaming on nanostructured superhydrophobic surfaces
Cheuk Wing Edmond Lam, Kartik Regulagadda, Matteo Donati +5
Jumping of coalescing condensate droplets from superhydrophobic surfaces is an interesting phenomenon which yields marked heat transfer enhancement over the more explored gravity-d…
