Abstract
Multiphase flow happens when two or more phases flow simultaneously. Its most common class is the gas-liquid combination, which is typical of many industrial applications and natural processes. The way the phases are distributed in the pipe geometry classifies what we call flow patterns. One of the most common flow pattern is the slug flow, which is characterized by a large gas bubble called Taylor bubble and a thin liquid film separating the bubble from the tube wall. The determination of parameters related to its hydrodynamics have great relevance, given the complexity of this flow and the risks of operation and accident that it can cause. This study uses the conductive probe and image technique to determinate the translation velocity of the gas phase in an ascending vertical slug flow. The results obtained by the conductive probe are compared to the results given by the image technique and from empirical correlations. The results obtained by the two techniques, taking into account their relative errors, showed reasonable agreement when compared.
