Statistical Evaluation of Liquid Phase Distributions in Gas-liquid Two-phase Flow : Froth and Huge Wave Flow Regim

Abstract

A statistical method is proposed to express the characteristics in interface on various sizes of liquid lumps appearing in both froth an huge wave flow regimes. Cross-sectional mean liquid holdup trances suggest that the interfacial structures fundamentally consist of base wave and liquid slug or huge wave. The determining procedures of the shape factors and probability density of wave crests are examined. In addition, typical examples of applying this method into air-water two-phase upward flow in a 18.0 mm inside diameter tube are presented.
