Experimental research investigates vibration characteristics of flexible risers in gas-liquid two-phase flow, highlighting implications for design optimization.
Key Points
The research aims to analyze how gas-liquid two-phase flow affects the vibration characteristics of flexible risers.
Conducted experimental research using non-intrusive measurement techniques.
Utilized high-speed cameras and pressure sensors to capture vibrational data and internal flow structures.
Analyzed the correlation between pressure variations and mass distributions on vibration responses.
Vibration response reaches maximum amplitude when liquid slugs flow through flexible risers.
Departure of liquid slugs reduces vibration response significantly.
The influence of mass distributions on vibration is greater than that of pressure variations.
