Analytical modeling for the heat transfer in sheared flows of nanofluids [PDF]

, 2012
We developed a model for the enhancement of the heat flux by spherical and elongated nano- particles in sheared laminar flows of nano-fluids. Besides the heat flux carried by the nanoparticles the model accounts for the contribution of their rotation to ...

Multi-year particle fluxes in Kongsfjorden, Svalbard [PDF]

Biogeosciences, 2018
Abstract. High-latitude regions are warming faster than other areas due to reduction of snow cover and sea ice loss and changes in atmospheric and ocean circulation. The combination of these processes, collectively known as polar amplification, provides an extraordinary opportunity to document the ongoing thermal destabilisation of the terrestrial ...

Simulation of neutrino and charged particle production and propagation in the atmosphere [PDF]

, 2006
A precise evaluation of the secondary particle production and propagation in the atmosphere is very important for the atmospheric neutrino oscillation studies.

An Unusual Energetic Particle Flux Enhancement Associated with Solar Wind Magnetic Island Dynamics

Astrophysical Journal, 2018
The possibility that charged particles are accelerated statistically in a “sea” of small-scale interacting magnetic flux ropes in the supersonic solar wind is gaining credence. In this Letter, we extend the Zank et al.

Charged particle motion and radiation in strong electromagnetic fields [PDF]

Reviews of Modern Physics, 2021
The dynamics of charged particles in electromagnetic fields is an essential component of understanding the most extreme environments in our Universe. In electromagnetic fields of sufficient magnitude, radiation emission dominates the particle motion and ...

Long-Term Changes of Particle Flux in the Canary Basin Between 1991 and 2009 and Comparison to Sediment Trap Records Off Mauritania

Frontiers in Earth Science, 2020
Eastern Boundary Upwelling Ecosystems (EBUEs) are associated with high biological productivity, high fish catch and they highly contribute to marine carbon sequestration.

The Roles of Suspension-Feeding and Flux-Feeding Zooplankton as Gatekeepers of Particle Flux Into the Mesopelagic Ocean in the Northeast Pacific

Frontiers in Marine Science, 2019
Zooplankton are important consumers of sinking particles in the ocean’s twilight zone. However, the impact of different taxa depends on their feeding mode.

Observation of radially inward turbulent particle flux in ETG dominated plasma of LVPD [PDF]

, 2017
Radially inward turbulent particle flux is observed in the core region of target plasma of Large Volume Plasma Device where electron temperature gradient (ETG) driven turbulence conditions are satisfied with threshold, ηETG=Ln/LT>2/3 [Mattoo et al., Phys.

Polar particle flux distribution and its spatial extent

Journal of Space Weather and Space Climate, 2023
Context: The main challenge in atmospheric ionisation modelling is that sparse measurements are used to derive a global precipitation pattern. Typically this requires intense interpolation or scaling of long-term average maps.

Efficient Particle Transfer to Depth in Oxygen Minimum Zones of the Pacific and Indian Oceans

Frontiers in Earth Science, 2020
The remineralization depth of sinking organic particles controls the efficiency of the biological carbon pump by setting the sequestration timescale of remineralized carbon in the ocean interior.
