Experimental Findings

This paper presents an experimental investigation that employed the acoustic emission (AE) technology to monitor sand transportation in two-phase flow. This investigation was undertaken on two phase (air-sand) flow in a horizontal pipe for varying Superficial Gas Velocities (VSG). The objective of this research programme is to develop a simple, non-invasive technique for monitoring of sand particle concentration levels in multi-phase flow conditions. The experimental findings show that AE absolute energy can be correlated with the size of sand, number of sand particles and Superficial Gas Velocity (VSG).

This paper has propose a new method (acoustic emission) to distinguish the pattern of gas-liquid two-phase flow in the horizontal pipe. The signals which got from the probe when multiphase flow pattern changes in the pipe and the four probe installed on the different position. Through the analysis of time domination, energy of wavelet, collected the signal features and shows there has a significant differences among the three typical flow patterns (bubbly flow, stratified flow, annular flow). Energy of wavelet can clearly represents the signal strength. This paper found that the acoustic emission as a new method to distinguish flow patterns have good effect can as a new technology for the study of gas-liquid two-phase.
