Abstract

The influence of ratchet aspect ratio and the shape of ratchet ridges on the motion of film boiling water droplet were investigated. Continuous rebounding behavior of the droplet was observed on micro ratchets with lower depths and round ridges. The residence time and flying time of rebounding droplets are independent of surface temperature. The terminal velocity increases but the number of rebounds decreases as the surface temperature increases in the range of 192 - 248°C. Copyright © 2010 by ASME.
