The mixing of binary fluids by stirrers is a commonplace procedure in many industrial and natural settings, and mixing efficiency directly translates into more homogeneous final products, more enriched compounds, and often substantial economic savings in energy and input ingredients. Enhancements in mixing efficiency can be accomplished by unorthodox stirring protocols as well as modified stirrer shapes that utilize unsteady hydrodynamics and vortex-shedding features to instigate the formation of fluid filaments which ultimately succumb to diffusion and produce a homogeneous mixture. We propose a PDE-constrained optimization approach to address the problem of mixing enhancement for binary fluids. Within a gradient-based framework, we target the stirring strategy as well as the crosssectional shape of the stirrers to achieve improved mixedness over a given time horizon and within a prescribed energy budget. The optimization produces a significant enhancement in homogeneity in the initially separated fluids, suggesting promising modifications to traditional stirring protocols.

“…Non-Newtonian fluid flow in porous media is of interest in many applications such as biological systems [1], food engineering [2], biomedical research [3], enhanced oil recovery (EOR) [4], as well as in the pharmaceutical, textile, polymer and composites industries [5], to list a few. Interest in this topic was strengthened after the formalization of viscous instability for two-phase flow in porous media [6], which contributed to intensify the use of aqueous species to increase water viscosity in EOR processes [7].…”
