Dean flow and vortex shedding in a three-dimensional 180$^\circ$ sharp bend

, 2018
We present a detailed analysis of the flow in a 180 sharp bend of square cross-section. Besides numerous applications where this generic configuration is found, its main fundamental interest resides in the co-existence of a recirculation bubble in the outlet and a pair of Dean vortices driven from within the turning part of the bend, and how their ...

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

Physics of secondary flow phenomenon and erosion characteristics in the injector of a Pelton turbine

Engineering Applications of Computational Fluid Mechanics
The Pelton turbine is widely used in the development of high-head hydraulic resources. However, in high-altitude mountainous regions, multiple sediment environments, along with secondary flows generated within the cross-sections of the turbine's ring and

Exploiting Device Deformability for Fluid and Particle Manipulation

Small, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Polar Lipid and Fatty Acid Profiles of Oat Groats Substantially Influenced by Field Management: A Comparison of Cultivars, Sowing Times and Fertilizer Composition

Plant, Cell &Environment, EarlyView.
ABSTRACT The polar lipids in oat grains are crucial due to their biological functions, nutritional quality, potential use in food flavour and processing, the protection they provide against biotic and abiotic stresses, and their ability to act as cellular signalling molecules.
