摘要: Void fraction and two-phase frictional pressure drop in microchannels were experimentally investigated. Using air and water, experiments were conducted in transparent circular microchannels with 1.1 and 1.45 mm inner diameters and in microchannels with semi-triangular (triangular with one corner smoothed) cross-sections with hydraulic diameters 1.09 and 1.49 mm. Gas and liquid superficial velocities were varied in the 0.02–80m/s and 0.02–8m/s ranges, respectively, and void fractions were calculated by analyzing …
