Abstract
Preliminary experiments on nucleate pool boiling using asymmetric micro ratchets with de-ionized (DI) water as the working fluid were investigated. Two brass surfaces were tested for comparison; one surface was manually polished while the second was composed of asymmetric ratchets with 30μm height and 150 μm period. Small test aquariums (114.8 mm × 54 mm × 152.4 mm) were fabricated and tested on a hot plate. Results show that the ratchet surface made significant heat transfer improvements over the polished surface. Copyright © 2011 by ASME.
