Statistical characteristics of the interfacial waves in horizontal gas-liquid two-phase stratified flow

<正> The study of the interfacial waves is very important in understanding and grasping the laws of the phase interface exchange dynamics in gas-liquid two-phase flow. Based on a series of experiments and investigations, the statistical characteristics of the interfacial waves in gas-liquid two-phase stratified flow in both time and frequency domains are presented. The statistical parameters with variations of the gas and liquid superficial velocities are analyzed and discussed.
