Signal Analysis of Characteristics Using Passive Acoustic Emission Technique in Gas-Solid Pipeline Flows
This paper investigates a case study of the use of a passive acoustic sensor for online measurement of the dilute phase gas-solid pipeline flows.The acoustic emission sensor is COLOR mounted externally on a stainless steel line conveying silica powders.For different experimental conditions, including the solid to air mass ratios from 0.6 to 1.4 and
