1 Bubble Dynamics and Boiling Heat Transfer in Microscale

Abstract:-Bubble dynamics and boiling heat transfer are received great attention in recent years, due to the wide applications in micro devices or systems. The literature is becoming rich in conventional microchannels. One should be careful to apply these results in silicon microchannels, which have much smoother wall surface and smaller channel size. The fundamental issues related to non-dimensional parameters, bubble nucleation, flow patterns, flow instabilities and heat transfer mechanisms are reviewed in this paper. Besides, future studies on the bubble dynamics and boiling heat transfer are suggested. Key-Words:- Microchannel, boiling, bubble nucleation, flow pattern, heat transfer
