Introduction Gas–liquid two-phase flow is a common occurrence in oil and gas production and transportation. Slug flow, the most common flow pattern in horizontal and near horizontal flows, is...
[31], proposed a unified mechanistic model for the liquid holdup of liquid slugs, which was based on the balance between turbulent kinetic energy of the liquid phase and surface free energy of dispersed gas bubbles. They subsequently devised a consolidated model, grounded in the dynamics of ...

A set of experiments was performed to study flow pattern suppression in horizontal air-water pipeflow by means of surfactant additive. Results suggest that addition of the surfactant to the gas-liquid flow significantly reduces the occurrence of slug flow. In addition, previously unreported flow patt...

A physical model for the prediction of gas holdup in liquid slugs in horizontal and vertical two phase pipe slug flow is presented. This model can also be used to yield the transition between elonganted bubbles and slug flow within the intermittent flow pattern. In addition a previously publish...
The response amplitudes are amplified by the increased translational velocity and slug length, entailing the increased flow-induced momentum and gravitational forces, as the gas-to-liquid flow rate ratio is increased. Consequently, higher vibration modes participate into the riser dynamics exhibiting a ...
