TLDR
In this article, a theory is presented which shows that the velocity of the bubbles consists of a component equal to the superficial liquid velocity, a component equivalent to the gas velocity and a component due to buoyancy.About:

Two-Phase Slug Flow
Yehuda Taitel,Dvora Barnea +1 more
TL;DR: In this paper, the authors introduce several options of modeling the hydrodynamic parameters and pressure drop using a unified approach that is applicable for the vertical, horizontal, and inclined cases of slug flow.

Hydrodynamics of Taylor Flow in Vertical Capillaries: Flow Regimes, Bubble Rise Velocity, Liquid Slug Length, and Pressure Drop
TL;DR: Two-phase flow hydrodynamics in vertical capillaries of circular and square cross sections were experimentally studied, using air as the gas phase and water, ethanol, or an oil mixture as the liquid phase as discussed by the authors.

Unified model for gas-liquid pipe flow via slug dynamics: Part 1: Model development
TL;DR: In this paper, a unified hydrodynamic model is developed for predictions of flow pattern transitions, pressure gradient, liquid holdup and slug characteristics in gas-liquid pipe flow at all inclination angles from -90° to 90° from horizontal.

Numerical simulation of the dynamics of two-phase gas—liquid flows in bubble columns
A. Lapin,A. Lübbert +1 more
TL;DR: In this article, a two-dimensional computational fluid dynamics study of the two-phase gas-liquid flow in bubble columns is presented, where the flow is modelled by a Navier-Stokes system of equations in an Eulerian representation, whereas the motion of the gas is modeled on a smaller scale by tracking individual bubbles or bubble clusters through the liquid in a Lagrangian way.

Particle segregation in fluidised binary mixtures
TL;DR: The particle segregation in fluidised beds consisting of different types of binary mixtures is shown to be governed by the same particle transport processes in this paper, and the significance of the particle transport parameters is discussed.
