Implication

Experimental assessment uncovers the vibration response and differential pressure behavior of gas-liquid two-phase flows in U-tubes, highlighting flow pattern effects.

Key Points

Gas-liquid two-phase flow induces vibrations in U-tubes significantly affecting pipeline stability under varying flow patterns.
Key findings reveal strong correlations between inlet-outlet differential pressure fluctuations and flow pattern transitions, especially during stratified plug flow changes.
An experimental system measured pressure and vibration acceleration simultaneously, addressing the fluid-structure interaction in U-tubes during gas-liquid flow.
Impact vibrations are most pronounced during transitions from stratified-plug to slug-wavy flow patterns, indicating potential pipeline integrity risks.
