... passages of Taylor bubbles and liquid patches induce momentum fluctuation. In the churn flow regime, periodic liquid structures of different time and length scales can lead to momentum fluctuation. amplitude multiphase flow assessment two-phase flow upstream oil & gas production monitoring...

... by a broadband spectrum with high amplitudes. These forces differ with flow regimes and are still difficult to predict. Therefore a joint industry project was setup to perform both large scale (6") flow tests and to qualify CFD procedures and settings to calculate these forces with sufficient accuracy...

... simulators is important. Two experimental series on severe slugging have been made in a S-shaped riser geometry (50mm inner diameter, 14 m length and 6.5 m height), one using viscous oil and the other using water as a reference. The experimental results are time recordings, amplitudes of pressure...

... m long providing an upstream gas volume that gives extra compressibility to the system, facilitating liquid accumulation at the riser base and subsequent terrain slugging. The experiments show that at constant gas flow rates, the severity/amplitude of the slugging in the riser increases to a maximum...
