A literature review of theoretical models for drop and bubble breakup in turbulent dispersions
Yixiang Liao,Dirk Lucas +1 more
TL;DR: A literature review on mechanisms and models for the breakage of bubbles and drops (fluid particles) in turbulent dispersions is presented in this paper, where four categories are summarized, namely, turbulence fluctuation, viscous shear stress, shearing off process and interfacial instability.
Journal ArticleDOI
A literature review on mechanisms and models for the coalescence process of fluid particles
Yixiang Liao,Dirk Lucas +1 more
TL;DR: In this article, a literature review on the mechanisms and models of coalescence of fluid particles is presented, and five categories are summarized, namely, turbulence fluctuation, viscous shear stress, capture in turbulent eddies, buoyancy and wake interaction.
Journal ArticleDOI
The inhomogeneous MUSIG model for the simulation of polydispersed flows
TL;DR: A generalized inhomogeneous multiple size group (MUSIG) model based on the Eulerian modeling framework was developed in close cooperation of ANSYS-CFX and Forschungszentrum Dresden-Rossendorf and implemented into the CFD code CFX as discussed by the authors.
Journal ArticleDOI
Validation of cfd models for mono- and polydisperse air-water two-phase flows in pipes
TL;DR: In this article, the authors present multiphase flow models for the description of mono-and polydisperse bubbly flows in the Eulerian framework of multi-phase flow modeling in ANSYS CFX.
Journal ArticleDOI
On the modelling of bubbly flow in vertical pipes
TL;DR: In this article, a simplified model focusing particularly on the radial gas volume fraction distribution, the bubble size distribution and the radial residence of bubbles dependent on their size were determined for different distances from the gas injection.
