Abstract

Flow patterns were investigated in vertical upward gas-liquid flow in a concentric and an eccentric annulus (eccentricity 50%). A new method for flow pattern identification is proposed based on probability density function analysis of conductance probe signals. Flow pattern maps have been constructed and mathematical models are proposed which predict the flow pattern transitions.
