A model of interfacial waves in annular two-phase flow at different gravity levels
Microgravity provides an ideal environment to study interfacial waves (small scale phenomena) without the dominating effects of gravity. In this paper, conductance probes were used to measure film thickness and liquid velocities. Physical models of interfacial waves are presented for vertical upward flow (+1g), vertical downward flow (−1g), and microgravity (μg), at different gas and liquid flow rates. Based on these studies, the predominant parameters and the features of the wave structure are discussed. A preliminary mathematical model was proposed for the interfacial waves.
