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:

Large Eddy Simulations of Flow Instabilities in a Stirred Tank Generated by a Rushton Turbine
TL;DR: In this paper, the authors investigated the flow instabilities in a baffled, stirred tank generated by a single Rushton turbine by means of large eddy simulation (LES) using sliding mesh method.

GPU-accelerated large eddy simulation of stirred tanks
Shuli Shu,Ning Yang +1 more
TL;DR: It is found that at least 4000 impeller revolutions in simulation is needed to achieve an obviously time-independent macro-instability frequency, so the solver developed is more suitable for the fast simulation of stirred tanks using only a desktop computer without the need of much finer grid resolution and supercomputers.

Investigation of turbulent fluid flows in stirred tanks using a non-intrusive particle tracking technique
TL;DR: In this paper, the radioactive particle tracking (RPT) technique was used to measure the turbulent flow field in a tank agitated by a PBT for the first time, and the behavior of the wall jet was investigated.

Numerical investigation of bend and torus flows¿Part II : Flow simulation in torus reactor
TL;DR: In this paper, a torus reactor with straight parts fitted with a marine impeller is investigated, and a numerical resolution of the steady-state flow is performed using a multiple reference frames (MRF) approach to represent the particular flow induced by the impeller in the geometry.
