Translation dynamics of evaporating sessile binary-mixture droplet populations
Debarshi Debnath, Anna Malachtari, George Karapetsas +5
The translation dynamics of two binary mixture droplets is investigated theoretically and is corroborated with experiments. The proposed model accounts for the effects of Marangoni…
Asymmetric freezing of a sliding droplet on an inclined surface
Sivanandan Kavuri, George Karapetsas, Chander Shekhar Sharma +1
We investigate the asymmetric freezing of a liquid droplet sliding on an inclined cold surface using numerical simulations based on the lubrication approximation. The combined effe…
Evaporation of sessile drops on a heated superhydrophobic substrate
Sivanandan Kavuri, Chander Shekhar Sharma, George Karapetsas +1
We experimentally investigate the evaporation dynamics of sessile water droplets on a micro-nano textured superhydrophobic aluminum substrate at various temperatures using shadowgr…
Evaporation-driven coalescence of two droplets undergoing freezing
Sivanandan Kavuri, George Karapetsas, Chander Shekhar Sharma +1
We examine the evaporation-induced coalescence of two droplets undergoing freezing by conducting numerical simulations employing the lubrication approximation. When two sessile dro…
