Bubble‐Size distributions and flow fields in bubble columns
TL;DR: In this paper, the population balance is simplified and reduced to a balance equation for the average bubble volume, which is used to predict the rate of bubble breakup and coalescence based on physical principles.
Journal ArticleDOI
Computational flow modelling and design of bubble column reactors
TL;DR: In this article, the authors reviewed the modelling efforts on the flow patterns published in the last 30 years with relatively more focus on the last 10 years, focusing on cylindrical bubble columns where results on flow pattern could be extended to the design.

Design and scale-up of the Fischer–Tropsch bubble column slurry reactor
Rajamani Krishna,S.T. Sie +1 more
TL;DR: In this paper, Fischer-Tropsch (FT) synthesis on a large scale is of interest, as a means of conversion of remote natural gas to high-quality products, particularly, liquid transportation fuels.

Modeling the hydrodynamics of multiphase flow reactors: Current status and challenges
TL;DR: In this paper, a 3D simulation of two-phase flow using, say, a million nodes, involves the solution of over nine million nonlinear equations at each time step; the size of the problem becomes much larger when energy and species bal- ances are included.

Slurry Reactors for Gas-to-Liquid Processes: A Review
Tiefeng Wang,Jinfu Wang,Yong Jin +2 more
TL;DR: A review of the recent studies on the slurry reactor for gas-to-liquid processes is given in this paper, with focus on the new trend of coupling the population balance model (PBM) into the computational fluid dynamics (CFD) framework to describe the complex bubble behaviors and gas-liquid interphase interactions.
