Two-phase flow characterization by nuclear magnetic resonance Original Research Article

The results presented in this paper demonstrate the ability of the PFGSE-NMR to obtain a complete characterization of two-phase flows. Different methods are proposed to characterize air-water flows in different regimes: stationary two-phase flows and flows in transient condition. Finally a modified PFGSE is proposed to analyze the fluctuations in stationary air-water bubbly flows.
