Microbial stabilization of grape musts and wines using coiled UV-C reactor

OENO One, 2020
UV-C light is well known for its germicidal properties and is widely used for water disinfection. However, its low penetration into absorbing liquids, such as wines and musts, reduces drastically the microbial inactivation effectiveness.

Dean-Flow Affected Lateral Focusing and Separation of Particles and Cells in Periodically Inhomogeneous Microfluidic Channels

Sensors, 2023
The purpose of the recent work is to give a better explanation of how Dean vortices affect lateral focusing, and to understand how cell morphology can alter the focusing position compared to spherical particles.

NUMERICAL STUDY OF THE STRUCTURE AND LOCAL TURBULIZATION OF THE FLOW IN A BLOOD VESSEL WITH A ONE-SIDE STENOSIS

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021
Results of large eddy simulation of three-dimensional flow in a model of the blood vessel with a one-side 70% stenosis at a Reynolds number of 1800 are presented. The Germano-Lilly model was used for subgrid viscosity evaluation.

Microfluidic systems for the analysis of the viscoelastic fluid flow phenomena in porous media [PDF]

, 2011
In this study, two microfluidic devices are proposed as simplified 1-D microfluidic analogues of a porous medium. The objectives are twofold: firstly to assess the usefulness of the microchannels to mimic the porous medium in a controlled and simplified ...

Analysis of Dean vortices and sediment distribution in inlet passage of nearshore pump stations under solid-liquid two-phase conditions

Applied Ocean Research
Dean vortices are secondary flow vortices formed by the coupling effect of centrifugal and viscous forces when fluid flows through curved pipes. In nearshore pump station inlet flow passages, inhaled sediment interacts with Dean vortices, complicating ...
