TLDR
In this article, numerical simulations of the flow field in baffled mixing tanks, based on three alternative methods, are presented and discussed, where the impeller is not explicitly simulated, and its effects are modelled by imposing suitable, empirically derived, boundary conditions to the external flow.About:

Effect of the turbulence models on Rushton turbine generated flow in a stirred vessel
TL;DR: In this article, a comparison of four turbulence models using for numerical simulation of the hydrodynamic structure generated by a Rushton turbine in a cylindrical tank was performed, where the finite volume method was employed to solve the Navier-Stokes equations governing the transport of momentum.

Flow behaviour of an agitated tubular reactor using a novel dynamic mesh based CFD model
TL;DR: In this article, the authors proposed a novel CFD model to study fluid dynamics and mixing mechanisms in the ATR system, which combines a soft-sphere collision model with a dynamic meshing approach to tackle structurestructure and fluid-structure interactions simultaneously.

Effects of baffle length on turbulent flows generated in stirred vessels
TL;DR: In this article, the effect of baffles length on turbulent flows in stirred tanks was studied by solving the Navier-Stokes equations in conjunction with the Renormalization Group (RNG) of the k-ɛ turbulence model.

Weidong Huang,Kun Li +1 more
TL;DR: In this paper, the authors proposed the multiple rotating reference frames approach (MRF) for the impeller boundary condition (IBC) approach, in which the vessel is divided into two parts: the inner zone using a rotating frame and the outer zone associated with a stationary frame.

Effect of Mixing on the Particle Size Distribution of Paracetamol Continuous Cooling Crystallization Products Using a Computational Fluid Dynamics–Population Balance Equation Simulation
TL;DR: In this article, a coupled computational fluid dynamics-population balance equation (CFD-PBE) simulation was developed in which the PBE was discretized using a high-resolution central scheme and solved simultaneously with CFD equations in ANSYS FLUENT 15.0 utilizing user-defined scalars.
