Abstract
This paper presents a set of experimental data of air-water flow patterns in a channel with a cross-section of 1×1 mm2. The ranges of the gas and liquid superficial velocities are 0.1-10 m/s and 0.2-7 m/s respectively. Bubble, bubble-slug, slug, and frothy flows are observed. The experimental 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, the transition quality in the drift-flux model is much smaller than that predicted by the empirical relations for the case of microgravity. It is shown that the mini-scale modeling is not effective to anticipate the bubble-slug transition of two-phase flow at microgravity.
