ABSTRACT:
Hydraulic transport is commonly used in mining for moving particles or ore concentrates in pipes over long distances with a water stream. Control and monitoring of this process require sensor technology that can obtain relevant characteristics of the two-phase flow. Within this work, we investigate the acoustic emission (AE) technology for monitoring a hydraulic system with different sand concentrations. The results show the strong relationship between friction behavior in the pipe and the measured AE signals. These results are key for further development of an AE-based flow monitoring system.
