A fundamental study on the heat transport characteristics in a pulsating heat pipe by using a forced oscillation system (Measurement of effective thermal conductivity)

Nihon Kikai Gakkai ronbunshu, 2015
Recently, highly efficient small heat transport devices have been required. In particular, pulsating heat pipes (PHP) have come to draw a lot of attention. The contribution of sensible heat transport and latent heat transport in oscillating working fluid,

First-principle based predictions of the effects of negative triangularity on DTT scenarios

Nuclear Fusion
Plasmas with negative triangularity (NT) shape have been recently shown to be able to achieve H-mode levels of confinement in L-mode, avoiding detrimental edge localised modes.

Heat transfer characteristics of flat plate heat pipe with closed meandering channel composed of sintered metal porous sidewalls

Journal of Thermal Science and Technology
Pulsating heat pipes (PHPs) are valuable for compact cooling applications. This study introduces a novel heat pipe design: a flat-plate heat pipe with a closed meandering channel and sintered metal porous sidewalls (porous HP).

Observed Subsurface Marine Heatwaves Driven by Subsurface Eddies in the Western Tropical Pacific Ocean

Geophysical Research Letters
Marine heatwaves (MHWs) are extreme warm water events with high impact, but the drivers of subsurface MHWs, particularly the role of subsurface eddies in the occurrence of subsurface MHWs, are unclear yet. Previous studies suggest that surface warm water

Thermodynamic decoupling in the deep-strong coupling regime

JPhys Photonics
In the deep-strong coupling (DSC) regime, the interaction between light and matter exceeds their bare frequencies, leading to an effective decoupling.

Core plasma fueling by fast inward particle transport after hydrogen pellet injection in Wendelstein 7-X

Nuclear Fusion
A large database of more than 1000 individual cryogenic hydrogen pellets injected into Wendelstein 7-X for plasma fueling was analyzed to improve the understanding of the three phases of the process: the ablation, deposition and transport of the pellet ...

Pacific Arctic sea ice loss resulting from atmospheric circulation-driven ocean heat transport

Environmental Research Letters
Arctic sea ice is disappearing rapidly, but the melt comes from two different pathways: direct surface warming and the movement of warm water into the Arctic. This study focuses on the latter, i.e.

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection

Geophysical Research Letters
Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

Thermal conductivity of nickel superalloy MAR-M247

Metalurgija, 2016
The paper presents the narrow connection between γ’ phase dissolving and values of thermal conductivity. In annealing process the free space among γ’ particles (blocks) changes in certain cycle from fine to rough and back to fine.
