Abstract
The frequent occurrence of multiphase flows in pipes has motivated a great interest in this research area. In addition, particular cases of liquid-liquid flows are usually found in petroleum industry. There is not a proper understanding for a significant number of phenomena observed in flows involving immiscible mixtures of oil and water, especially when oil is significantly viscous. This research aims to obtain detailed liquid-liquid flow data through a fast-response electrical-impedance wire-mesh sensor, using test facilities installed at the Thermal-fluids Engineering Laboratory of EESC-USP and data from the literature. The tomographic data obtained via wire-mesh sensor is useful for developing new models of transition and equations that can improve numerical codes applied in projects of directional oil well or wells equipped with gravitational gas separators. The study of the effect of the phases’ volumetric-fraction distribution allows the adjustment of the existent mathematical models based on data from two-phase flows with oils of low viscosity. The analysis of the data gives not only the position of the interface, but it also gives which is the dominant phase. This information is useful for the experimental determination of entrainment factors in stratified flow. The obtained results are unprecedent in the literature, and, they will allow to make comparisons with existent data in order to evaluate whether some potential discrepancies detected in the phase fraction distributions have physical cause or occur due to limitation of the instrumentation.
