| Résumé : |
Flow boiling of HFE 7000 in five parallel microchannels of 222 µm hydraulic diameter, each containing a single row of 24 in-line 100 µm pin fins, was investigated. High speed photography revealed the dominant flow patterns, namely, the bubbly flow, the multiple flow, and the wavy-annular flow. The interaction of the bubble with the pin fins during nucleate boiling from G=350 kg/m2 s to G=827 kg/m2 s and wall heat fluxes from 10 W/cm2 to 110 W/cm2 is detailed.
