TL;DR: In this paper, a systematic experimental investigation of two-phase flow patterns in microchannels was the objective of this study, using air and water, experiments were conducted in circular micro channels with 1.1 and 1.45mm inner diameters, and in semi-triangular (triangular with one corner smoothed) cross-sections with hydraulic diameters 1.09 and 149mm.

TL;DR: In this paper, the authors investigated void fraction and two-phase frictional pressure drop in transparent circular microchannels with 1.1 and 1.45mm inner diameters and in semi-triangular (triangular with one corner smoothed) cross-sections with hydraulic diameters 1.09 and 0.49mm.

TL;DR: Onset of nucleate boiling and onset of flow instability in uniformly heated microchannels with subcooled water flow were experimentally investigated using 22 cm long tubular test sections, 1.17 mm and 1.45 mm in diameter, with a 16-cm long heated length.

TL;DR: In this paper, the authors investigated the effect of abrupt flow area expansion and contraction in small circular channels, using air and water at room temperature and near-atmospheric pressure as the working fluids.
