NUCLEATION AND THERMODYNAMIC NONEQUILIBRIUM FOR BOILING IN MICROCHANNELS AND MICROSTRUCTURES
We review recent experimental and theoretical investigations that have contributed to developments and advances in boiling phase-change and transport phenomena in microchannels and microstructures, including bubble formation during boiling, phase transition, and the fluid flow and heat transfer characteristics. These investigations showed that bubble formation and phase transition in open and confined microstructures and the flow boiling heat transfer of pure water, pure methanol, and water-methanol binary mixtures through rectangular and triangular microchannels display some unusual phenomena and characteristics. The experimental results showed that the microchannel size, the geometric configuration including the aspect ratio (H/W) of the rectangular microchannels and the groove angle (6) of triangular microchannels, and the mole fraction of water-methanol binary mixtures have a significant impact on the flow boiling, especially for nucleate boiling, and on bubble formation and growth in microchannels.
