Evaporation of microdroplet on a heated plate at 408 K

Research output: Contribution to journalConference articlepeer-review

Abstract

Droplet-based cooling systems require a detailed data on droplet evaporation at relatively high substrate temperature. We investigate the dynamics of water droplet evaporation on a heated sapphire substrate for the substrate temperature of 408 K. The stable (not boiling) evaporating droplet of 0.33 μl volume forms immediately just after boiling process when the temperature is still higher than boiling temperature of the liquid. Stick-slip motion is observed with the first depinning at 0.07 μl in volume. Total evaporation time is 1.13 sec.
