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:

Chaotic Mixing Intensification and Flow Field Evolution Mechanism in a Stirred Reactor Using a Dual-Shaft Eccentric Impeller
TL;DR: In this article , a dual-shaft eccentric impeller based on the RT and pitched blade Rushton turbine (PBRT) was proposed to eliminate the stable symmetrical flow field structure in the mixing tank and improve the fluid transfer efficiency and chaotic mixing degree.
