Self-sustained biphasic catalytic particle turbulence
Nature Communications, 2019 Turbulent systems are particularly suitable for heat transport. Here the authors add active particles to a turbulent system, and the coupling of turbulent convection and the collective dynamics of active particles leads to a 500% enhancement in heat ...

Multiscale Turbulent Transport [PDF]
, 2020 Turbulent transport is currently a prominent and ongoing investigation subject at the interface of methodologies from theory to numerical simulations and experiments, and it covers several spatiotemporal scales. Mathematical analysis, physical modelling, and engineering applications represent different facets of a classical, long-standing problem that ...

Turbulence-driven vortex-flow around a magnetic island
Nuclear Fusion, 2023 We predict a new state of plasma self-organization, in the presence of magnetic islands, namely turbulence-driven island vortex-flows, which are non-axisymmetric flows.

Turbulence Suppression in Transport Barriers
Fusion Science and Technology, 2004 Basic facts about transport barriers in toroidally confined plasmas are presented. The flow shear of poloidal plasma rotation is a common feature in the spontaneous and induced transport barriers as well and is considered as the basic cause of their formation. Basic ideas on the impact of flow shear on the radial transport are discussed.

Scalar Transport Characteristics Near the Turbulent/Non-Turbulent Interface in a Reactive Jet Flow
气体物理Turbulent/non-turbulent interface (T/NTI) layer separates the turbulent and non-turbulent regions. The study of T/NTI is helpful to deepen the understanding of mass transfer between turbulent and non-turbulent regions.

Estimation of Turbulent Triplet Covariances for Bora Flows
Fluids, 2021 Bora is a strong or severe, relatively cold, gusty wind that usually blows from the northastern quadrant at the east coast of the Adriatic Sea. In this study bora’s turbulence triplet covariances were analysed, for the first time, for bora flows.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Nuclear Materials and Energy, 2017 Transport codes are the main workhorses for global edge studies and modern divertor design. These tools do not resolve turbulent fluctuations responsible for the bulk of cross-field transport in the Scrape-off Layer (SOL), and solve mean field equations ...
