Journal ArticleDOI
Vibration sensor approaches for sand detection in oil–water–sand multiphase flow
TL;DR: In this paper, a wideband vibration sensor was used to monitor sand-water and sand-oil-water flows in pipeline, and the experimental results showed that there is an obvious correlation between vibration power spectrum amplitude and sand concentration.
Journal ArticleDOI
Acoustic sensor approaches for sand detection in sand–water two-phase flows
TL;DR: In this article, an acoustic focusing component is designed to assist a condenser microphone in detecting the sand signals, and a time-frequency analysis method and a characteristic sand frequency multiband digital filter method are presented to enhance the sand detection in water flows with strong background noise.
Journal ArticleDOI
Spatially resolved in situ measurements of the ion distribution near the surface of electrode in a steady-state diffusion in an electrolytic tank with confocal micro X-ray fluorescence.
TL;DR: The confocal MXRF has potential applications in spatially resolved analysis of the liquid mass transfer in electrolytic tanks in situ and in situ analysis of ion distribution near the surface of the electrode in a steady-state diffusion in an electrolytic tank.
