Study of the application of Acoustic Emission technology for on-line monitoring of bubble phenomena and flow patterns in two-phase gas-liquid flow

摘要

An investigation into single bubble dynamics detection in a liquid-filled column, and monitoring and measurement of gas void fraction in a horizontal pipe using AE technology has been performed. A correlation between Acoustic Emission (AE) and Gas Void Fractions in two-phase gas-liquid flow in a horizontal pipe has been established from this work. The results demonstrate the feasibility of employing AE technology as an on-line monitoring tool for bubble dynamics and flow patterns in two-phase gas-liquid flow in pipes.
