摘　　要：This paper presents a statistical method to calculate local interfacial variable s in horizontal gas-liquid bubbly flows based on the data measured with a double -sensor probe.The geometrical relationship between the apparent and actual bubbl e velocities and the relationship between the chord intersected by the sensor an d bubble diameter were determined.A probability density function was introduced to consider the effect of both axial and radial movements of bubbles on bubble v elocity and bubble size.This paper presents a statistical method to calculate local interfacial variable s in horizontal gas-liquid bubbly flows based on the data measured with a double -sensor probe.The geometrical relationship between the apparent and actual bubbl e velocities and the relationship between the chord intersected by the sensor an d bubble diameter were determined.A probability density function was introduced to consider the effect of both axial and radial movements of bubbles on bubble v elocity and bubble size.
