Flow boiling heat transfer in microchannels
WebJul 11, 2012 · Integrated two-phase microchannel liquid-cooling technology has been envisioned as a promising solution, but with great challenges in flow instability. In this work, silicon nanowires were synthesized in situ in parallel silicon microchannel arrays for the first time to suppress the flow instability and to augment flow boiling heat transfer. http://www.globalauthorid.com/WebPortal/ArticleView?wd=4C5A8D0827CA78F7307A1A8153253F74F3899DC5C129D2EEF4FA280186A308C41FEC699F4775217F
