The mixing process in a mechanically agitated vessel is a widespread phenomenon which
plays an important role among industrial processes. In that process, one of the crucial …

In the first part of the review, published literature regarding the CFD modelling of single‐
phase turbulent flow in stirred tank reactors with radial flow impellers was critically analysed …

A combined computational fluid dynamics (CFD) and population balance model (PBM)
approach has been applied to the simulation of gas–liquid stirred tanks agitated by (i) a …

Drag force plays important roles in the prediction of gas-liquid flow in stirred tanks, but
systematic studies on drag models are still lacking. In this study, we evaluated the effect of …

This work is aimed at investigating the turbulent two-phase flow and the bubble size
distribution (BSD) in aerated stirred tanks by experiments and computational fluid dynamics …

A comprehensive computational fluid dynamics CFD model was developed in the present
study to gain insight into the solid suspension in a stirred slurry reactor. The preliminary …

Computational fuid dynamics (CFD) is an increasingly important tool for carrying out realistic
simulations of process equipment. In the case of multiphase systems the development of …

The production rate of fed-batch aerobic fermenters is often limited by the oxygen transfer
rate that depends on the fluid dynamics of the gas-liquid system. In turn, ideal flow regimes …

A three-dimensional CFD model was developed in this work to simulate hydrodynamic
characteristics of a gas–liquid two-phase stirred tank with two six-bladed turbines and four …

A novel method was proposed to determine the flow regime based on the bottom pressure
fluctuations of the stirred tank. Statistical, Hurst, Shannon entropy and chaos analysis …
