Journal ArticleDOI
Self-cleaning of superhydrophobic surfaces by self-propelled jumping condensate
Katrina M. Wisdom,Jolanta A. Watson,Xiaopeng Qu,Fangjie Liu,Gregory S. Watson,Chuan-Hua Chen +5 more
TL;DR: The jumping-condensate mechanism is shown to spontaneously clean superhydrophobic cicada wings, where the contaminating particles cannot be removed by gravity, wing vibration, or wind flow.
Journal ArticleDOI
Hotspot cooling with jumping-drop vapor chambers
Kris F. Wiedenheft,H. Alex Guo,Xiaopeng Qu,Jonathan B. Boreyko,Fangjie Liu,Kungang Zhang,Feras Eid,Arnab Choudhury,Zhihua Li,Chuan-Hua Chen +9 more
TL;DR: In this paper, a jumping-drop vapor chamber consisting of parallel plates of a superhydrophilic evaporator and a super-hydrophobic condenser is proposed to address mobile hotspots with a pathway toward effective thermal transport in the out-ofplane direction.
Journal ArticleDOI
Self-propelled sweeping removal of dropwise condensate
Xiaopeng Qu,Jonathan B. Boreyko,Jonathan B. Boreyko,Fangjie Liu,Rebecca L. Agapov,Nickolay V. Lavrik,Scott T. Retterer,James J. Feng,C. Patrick Collier,Chuan-Hua Chen +9 more
TL;DR: In this paper, a substrate design with regularly spaced micropillars is proposed to enhance dropwise condensation in a self-sustained manner, where the condensate drops spontaneously jump in a direction nearly orthogonal to the pillars and parallel to the substrate.
Journal ArticleDOI
Self-Propelled Droplet Removal from Hydrophobic Fiber-Based Coalescers
TL;DR: This Letter reports self-propelled removal of drops from a hydrophobic fiber, where the surface energy released upon drop coalescence overcomes the drop-fiber adhesion, producing spontaneous departure that would not occur on a flat substrate of the same contact angle.
Journal ArticleDOI
Enhanced flow boiling in microchannels using auxiliary channels and multiple micronozzles (I): Characterizations of flow boiling heat transfer
TL;DR: In this article, a four-nozzle configuration was developed with an aim at extending the highly desirable mixing effect to the entire channel, where the onset of nucleate boiling temperature was considerably reduced by ∼14% because of more nucleation sites created by the multiple nozzles.
