Today, increasing energy costs require effective processes, especially in chemical and pharmaceutical industries. Particularly, energy-intensive mixing processes offer high potential for optimization. Despite great efforts of research mixing of liquid-liquid components is not completely predictable. To construct mixing systems, empiricism is used rather than basic knowledge. Local mixing qualit...

We investigate the temporal scaling properties of mixing in heterogeneous permeability fields with variances ranging from very small (σ lnK = 0.01) to very large (σ lnK = 9). We quantify mixing by the scalar dissipation rate, which we estimate over a large range of temporal scales. For an initial pulse line injection, we find that moderate and strong heterogeneity induce Preprint submitted to E...

Incomplete mixing of reactive solutes is well known to slow down reaction rates relative to what would be expected from assuming perfect mixing. In purely diffusive systems, for example, it is known that small initial fluctuations in reactant concentrations can lead to reactant segregation, which in the long run can reduce global reaction rates due to poor mixing. In contrast, nonuniform flows ...

In this study, poly carbonate (PC) and poly (ethylene terephthalate) (PET) were reactive melt-blended under two different conditions to produce PC/PET copolymers. For each condition, samples were taken at specified mixing times representative a specific structure of copolymers and each one employed to physically compatibilize a PC/PET blend with a fixed composition. Reactive blending and copoly...

Over the years, multi-agent systems (MAS) technologies have shown their usefulness in creating distributed applications focused on autonomous intelligent processes. For this purpose, many frameworks for supporting been developed, normally oriented towards a particular type of agent architecture (e.g., reactive or deliberative agents). It is common, example, platform BDI (Belief, Desire, Intenti...
