Abstract
A special experimental loop is designed and constructed to study the characteristics of the void fraction of gas-liquid two-phase flow in vertically-downward pipes. The test section is made of transparent pipe with a length of 6Â m and an internal diameter of 25Â mm. The void fraction ranging from 0.1 to 0.98 widely is measured using quick-closing valve method. It is found that the range of the void fraction could be divided into three regions with different flow patterns and different relationships between the void fraction and the gas-liquid volumetric flow rate ratio. Moreover, 39 correlations for calculating the void fraction collected from present literature, are classified, and evaluated using the experimental data obtained in this study. The prediction of correlations in the literature needs to be improved when the void fraction is small.
