On the lifetimes of evaporating droplets

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.

Web8 de mai. de 2015 · It is therefore concluded that, for increasing substrate heating, the evaporation rate increases more rapidly in the CR mode than in the CA mode. In other words, the higher the temperature the larger the difference between the lifetimes of an evaporating drop in the CA mode with respect to that evaporating in the CR mode. WebIn both situations we find that the lifetimes of the droplets are significantly extended relative to those when thermal effects are weak.
