小通道内气液两相流动中Taylor气泡界面演化过程的实验研究

In order to investigate the interface morphology of Taylor bubble gas-liquid two-phase flow, visual experiment was studied in narrow space channels with different diameters with different gases as working fluid. The gas-phase working fluieds inclued air, nitrogen, argon and carbon dioxide gas, and the liquid-phase working fluid is water. . The test-sectiones for the visual experiments are vertical plexiglass pipes with inner diameters of 1 mm, 2 mm, 3 mm and 6 mm. Based on the visual experimental study, the interface morphology of Taylor bubble was obtained, with different channel inner diameters, different gas flows and different of gas-phase working fluieds; the effect of properties (including Eo number and Mo number) of gas-phase working fluids on the evolution of Taylor bubble interface was analyzed in this paper.
