Abstract
Void fraction has been measured for the gas-liquid cocurrent slug flow in 8mm vertical acrylic tube using an optical method. Bubble speed, length and period could be measured with the two sets of laser-infrared sensor modules mounted 25mm apart alongside the tube, which were designed to detect variation of light intensities with a time delay when two parallel laser beams were refracted successively by a passing bubble. It was found that the results were in good agreement with the previous studies in the literature suggesting that the method used in this study were sound and accurate.
