Measuring Slugging Bed Dynamics with Acoustic Sensors

Measuring Slugging Bed Dynamics with Acoustic Sensors

We describe experimental observations of slugging bed dynamics with passive acoustic sensors. Our results indicate that acoustic signals contain both similar and complementary information relative to dynamic pressure signals. We find that sele...
