An investigation on phase distribution in air-water two-phaseflow in horizontal circular channel was conducted by using the double-sensor resistivity probe. The variations of phase distribution with variations ofgas and liquid volumetric fluxes were analyzed and the present data werecompared with some of other researcher's data and existing models. It wasfound there exists more complicated phase distribution pattern in horizontalflow system than in vertical flow. The radial local void fraction profilesare similar at the same measurement angle with various gas and liquid flowrates. However, an asymmetric profile can be observed at a given slice ofthe pipe cross-section.
