Abstract
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 and bubble diameter were determined.A probability density function was introduced to consider the effect of both axial and radial movements of bubbles on bubble velocity and bubble size.
