摘要：
Flow boiling of HFE 7000 on micro pin fins entrenched inside microchannels was experimentally studied for G = 350 kg/m(2)s to G=827 kg/m(2)s and wall heat fluxes from 10 W/cm(2) to 110 W/cm(2). Bubbly, multiple, and wavy-annular flow patterns were observed. The interaction of the bubble with the pin fins during nucleate boiling is detailed.
