Abstract:In this paper the interfacial characteristics of a liquid flowing over a 1cm2 array of hydrophobic cylindrical micropillars located within a microchannel are investigated. The microchannel was 12mm wide and 32mm long with an average channel height of approximately 83μm. Hydrophobic coating of the channel was achieved via a controlled flow of a trichlorosilane and ethanol solution. A method to remove lodged gas bubbles from a microchannel was successfully demonstrated, while maintaining the favorable Cassie-Bax… Show more
