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:

TL;DR: In this paper, an ultrasound pulsed doppler device was used to measure the axial velocity of Xanthan Gum solutions behind cooling coil banks in two large (300 and 20,000 gal) fermentors, agitated by multiple down-pumping A315 impellers.

CFD Study of the Fluid Viscosity Variation and Effect on the Flow in a Stirred Tank
TL;DR: In this article, the effect of varying the fluid viscosity in a stirred tank with a Rushton turbine was studied using the software Fluent, where three viscosities (0.9%, 1.1%, and 1.7%), i.e., carboxymethylcellulose (CMC), were considered.

A geometric approach for predicting vertical stationary profiles of weakly inertial advecting-diffusing particles in closed incompressible flows
TL;DR: In this paper, the qualitative and quantitative features of the vertical particle distribution (i.e., the horizontal cross-sectional averages of particle concentration) can be predicted from the structure of the flow resulting from the superposition of the stirring field and the settling velocity.
