Numerical prediction of flow fields in baffled stirred vessels: A comparison of alternative modelling approaches
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:

A CFD-Based Model for Predicting Shear-Induced DNA Breakage in Mix Tanks
TL;DR: Experimental data indicates that the CFD models, employi g a RNG turbulence model and a dense numerical grid around the impeller, predict reasonably well the size of the “high-shear” zone in mixing tanks.

Simulation of solid–liquid suspension and scale-up of agarose gel activation reactor
TL;DR: In this paper, the effect of impeller configuration was studied with three typical impellers, including Rushton disk turbine (DT), pitched blade downflow turbine (PBTD45), and pitched blade upflow turbine(PBTU45), with a diameter of 100mm and critical suspension speed of 570rpm.

TL;DR: In this paper , the performance of different dual-shaft eccentric mixers at the constant power input with its fluid velocity profiles, average shear strain rate, mixing time and mixing energy was investigated.
Estudo em CFD sobre a influência da configuração da chicana em tanques de mistura
TL;DR: In this paper, the authors analyse the influence of different formatos of chicanas on a tanque agitado with an impelidor PBT, with the aim of quantifying the effect of these formatos on the consumption of energy.
