Transport barriers are observed inhibitors of the spread of substances in flows. The
collection of such barriers offers a powerful geometric template that frames the main …

Engineered injection and extraction (EIE) is an in situ groundwater remediation strategy that
imposes an engineered spatially and temporally varying velocity field to spread an …

Twin-screw extruders (TSEs) are known for their good mixing performance. Although global
mixing performance has been the subject of many computational fluid dynamics studies, the …

In this paper, we present an innovative sine-helical heat exchanger whose channel
geometry consists in a combination of a helically coiled geometry and a sine-wave …

Taylor-Aris dispersion represents an undesired phenomenon in pressure-driven liquid
chromatography, often responsible for the unchecked increase of the Height Equivalent of …

Historically, the dominant conceptual paradigm of porous media flow, solute mixing and
transport was based on steady two-dimensional flows in heterogeneous porous media …

In the context of in situ groundwater remediation, mixing is vital for a successful outcome. A
slow mixing rate between the contaminated groundwater and the injected treatment solution …

Flow and mixing characteristics of a thixotropic fluid in a static mixer were numerically
investigated in this study. We selected a barrier-embedded partitioned pipe mixer (BPPM) as …

The Lagrangian transport in the laminar incompressible flow in a two-dimensional square
cavity driven by a harmonic tangential oscillation of the lid is investigated numerically for a …

During in situ groundwater remediation, reactions occur in a narrow reaction front in which
the amendment and contaminant are close enough to mix. Active spreading, in which …
