Ultrasound Measurement of Large Bubbles in Slug Flows
Recent research by Dr Dongik Yoon introduces an innovative ultrasonic method for measuring bubbles in high-velocity slug flows, offering a precise approach to understanding complex fluid dynamics: Ultrasound measurement of large bubbles rising in angled slug pipe flows.
This innovative technique uses Ubertone’s UB-Lab UVP (Ultrasonic Velocity Profiler) for combining echo intensity and Doppler velocity data to accurately detect bubbles in challenging flow conditions. The method offers several key advantages:
- Non-invasive measurement
- Applicability to opaque fluids
- Simplified installation compared to optical systems
- High-resolution data capture
The researchers validated their approach against image processing techniques, demonstrating its effectiveness across various flow conditions. This breakthrough has significant implications for industries dealing with complex multiphase flows, such as oil transportation, chemical engineering, and airlift pump systems.
