Thermal front analysis of detached divertors and MARFEs [PDF]

Nuclear Fusion, 1994
A non-linear analysis is presented of localized regions of strong divergence of parallel heat flux-thermal fronts-in the edge and scrape-off layers of tokamaks. The phenomena of divertor detachment and MARFEs are discussed in terms of one dimensional thermal conduction in the parallel co-ordinate, but retaining cross-field transport power divergence ...

Experimental studies and modeling of complete H-mode divertor detachment in ASDEX Upgrade

, 2015
Power exhaust in future fusion devices is critical and operation with a detached divertor is foreseen for ITER and DEMO. The evolution of detachment in nitrogen seeded H-mode discharges at ASDEX Upgrade is categorized in four phases.

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

Journal of Quaternary Science, EarlyView.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Role of molecular effects in divertor plasma recombination

Nuclear Materials and Energy, 2017
Molecule-Activated Recombination (MAR) effect is re-considered in view of divertor plasma conditions. A strong isotopic effect is demonstrated. In deuterium plasmas, the reaction chain through D2+ formation, usually considered dominant and included in 2D

A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

2D analysis of tokamak divertor-plasma detachment-bifurcation with operational parameters and geometries

Nuclear Materials and Energy
UEDGE simulations with density scans for various input power, transport coefficients and outer poloidal leg length are performed to study the conditions for the existence of a bifurcation-like drop of Te at the outer strike point, commonly referred to as

Physics design for a lithium vapor box divertor experiment on magnum PSI

Nuclear Materials and Energy, 2019
The lithium vapor box divertor is a potential solution for power exhaust in toroidal confinement devices. The divertor plasma interacts with a localized, dense cloud of lithium vapor, leading to volumetric radiation, cooling, recombination, and ...

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain

Land Degradation &Development, EarlyView.
ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...

Millennials' Hybrid Consumer Identities: Balancing Consumer Ethnocentrism

Psychology &Marketing, EarlyView.
ABSTRACT While consumer ethnocentrism has been widely examined, little is known about how consumers manage the persistent gap between ethnocentric attitudes and everyday purchasing behavior. Drawing on balance theory (Heider 1958), this study conceptualizes consumer ethnocentrism as a situationally activated balancing process rather than a stable ...
