Gas bubbles are of major importance in most metallurgical processes. They promote
chemical reactions, homogenize the melt, or float inclusions. Thus, their dynamics are of …

This work reviews the state‐of‐the‐art models for the simulation of bubble columns and
focuses on methods coupled with computational fluid dynamics (CFD) where the potential …

A generalized inhomogeneous multiple size group (MUSIG) model based on the Eulerian
modeling framework was developed in close cooperation of ANSYS-CFX and …

In this paper, the volume of fluid (VOF) model in conjunction with continuum surface force
(CSF) model was used to numerically investigate the single bubble formation and dynamics …

This paper presents a VOF-based numerical method for simulating mass transfer across
deformable fluid interfaces. The underlying mathematical model is based on continuum …

For the simulation of bubbly flows, knowledge of the lift force as an interaction between gas
bubbles and a surrounding shear field is of great importance. The sign of the lift coefficient …

The transient simulation of large scale bubbly flow in bubble columns using the unsteady
Reynolds averaged Navier Stokes (URANS) equations is investigated in the present paper …

This paper provides a comprehensive explanation for the lift force acting on a freely
deformable bubble rising in a linear shear flow and examines how the lift force scales with …

In recent years CFD has proven itself as a valuable tool for gaining insight in flow
phenomena in general and complex multiphase flows arising in process equipment in …

The lift force, which strongly influences the spatial bubble distribution, is one of the most
important non-drag forces. However, measurements in systems with a low Morton number …
