Enhanced Flow Boiling in Micro-channels by High Frequency Micro-bubble-excited and -Modulated Oscillations

Technology Area: Materials & Chemical

Commercial Maturity: Prototype

Abstract: This invention is a micro-channel architecture consisting of a main-channel and two auxiliary-channels connected at a cross-junctions in a unit. It dramatically enhances flow boiling in micro-channels. The novel actuation mechanism powered by the high frequency micro-scale vapor bubble growth/collapse creates and sustains strong-mixing in micro-channels.
