ABSTRACT A visualization method using image processing to observe the flow pattern of air-water mixtures in microchannel is developed. A high-speed camera is used to identify the flow regimes. A 250-mm-long and 1-mm-inner diameter circular glass tube is used as the test channel. Air and water flow rates range from 0.01 to 0.1 L/min and 0.3 to 0.9 L/min, respectively. The results report that all observed flow patterns are annular. In addition, the comparison between the present experimental data and well-known two-phase flow pattern maps available in the literature is presented. |
