AbstractThis paper presents a new set of experimental data of air-water flow patterns in a channel with a cross-section of 1x1 mm(2). The ranges of the gas and liquid superficial velocities are 0.1 similar to 10 m/s and 0.2 similar to 7 m/s, respectively. Bubble, bubble-slug, slug, and frothy flows are observed. The present data are compared with other data in mini-channels reported in literature, and also compared with those in normal channel at microgravity, in which the Bond number has the same order of magnitude. The slug-frothy boundary is in consistent with each other, but for the bubble-slug transition, a much smaller value for the transition quality in the drift-flux model is obtained in the present study than those predicted by the empirical relations for the case of microgravity. It's shown that the mini-scale modeling may not be an effective way to anticipate the bubble-slug transition of two-phase flow at microgravity.
