Self-Oscillatory Loop Flow of an External Air-Lift Loop

摘要: Abstract The present experimental investigation revealed that the hydrodynamic behavior of external air-lift loop deviates significantly from its normal when it is operated under low liquid inventory. To capture this excursive a micro-processor based magnetic flowmeter placed in line with downcomer and recorded temporal flow rate variation. signals are analyzed rigorously using different techniques nonlinear dynamics such as FFT, scatter, time delay plots along visual observations. Investigations show increase air injection riser, oscillations through increases, shifts periodic to chaotic nature. diversity has major influence on regime formation riser clear transformation observed visually slug churn flow.
