On the lifetimes of evaporating droplets
WebAbstract. The complete description of the lifetime of a droplet on a solid substrate evaporating in a 'stick–slide' mode is obtained. The unexpectedly subtle relationship betwee Web20 de jan. de 2016 · For small separation distance, the droplets undergo asymmetric spatiotemporal evaporation leading to contact angle hysteresis and suppressed vaporization. The reduced evaporation has been attributed quantitatively to the existence of a constrained vapor-rich dome between the two droplets.
