- ABSTRAK The research was about void fraction measurement of gas-liquid (air-water) two-phase flow in upward co-current ,ertical pipe. The diameter of the pipe was 24 mm, with 2250 mm length of the measurement. The goal of the research is to have special study of the void fraction measurement's performance while the hand operated quick closing valve technique was used. The determination of the performance was measured by using theoretical nodels as analytical tools, i.e., the homogeneous model, the Lockhard-Martinelli separated flow model, and the drift flux nodel. The using of more than one theoretical models were to have complete analysis and comparison between each nodels to the others and each models to the experimental method. The observation was made by altering the liquid flow late, and for each liquid flow rate the gas flow rate was also altered. The result of the research indicates that the void fraction increased for the increasing of gas flow rate. It was also round that the performances of the quick closing valves possessed distinct results occur for each of theoretical models lepend on the regimes of the stream. Key word : gas-liquid, void fraction, homogeneous, separated flow, drift flux.
