SOLPS-ITER modification for impurity transport modelling in the tokamak pedestal region

Nuclear Materials and Energy
Kinetic corrections to SOLPS-ITER fluid equations are made to extend their applicability for description of the neoclassical part of impurity transport to collisionless regimes of the main ions.

Neoclassical transport of toroidal momentum in tokamaks

Physical Review Letters, 1990
La presence d'une concentration moderee (∼10%) d'ions de basses energies en exces par rapport a la distribution maxwellienne provoque un changement dramatique dans la prediction neoclassique du transport de la quantite de mouvement, conduisant a un accord en magnitude avec l ...

Transition in particle transport under resonant magnetic perturbations in a tokamak

Nuclear Fusion, 2023
Nonlinear 3D MHD simulations and validations reveal that the hybrid particle-MHD transport is a key process for driving the pump-out in the presence of Resonant Magnetic Perturbations (RMPs) in the KSTAR tokamak.

Neoclassical transport in high {beta} tokamaks [PDF]

, 1992
Neoclassical, transport in high [beta] large aspect ratio tokamaks is calculated. The variational method introduced by Rosenbluth, et al., is used to calculate the full Onsager matrix in the banana regime. These results are part of a continuing study of the high [beta] large aspect ratio equilibria introduced in Cowley, et al.

Corporate Environmental Responsibility and Cost of Equity Capital: A Meta‐Analytical Review

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite extensive research on the relationship between corporate environmental responsibility (CER) and cost of equity capital (COEC), empirical evidence remains inconsistent. This study addresses these inconsistencies through a comprehensive meta‐analysis of 1139 effect sizes from 75 studies.

Comparable levels of turbulent and neoclassical transport of high-Z impurities: integrated modelling in AUG, JET and C-Mod

Nuclear Fusion
Operation with beam heating is prone to central accumulation of high- Z impurities in present-day tokamaks due to a dominant neoclassical pinch. Fusion reactors are expected to have a different core transport regime for high- Z impurities, where ...

Initiating Market Formation Through Local Policy Innovation: Plot Handover as a Driver for Circular Construction

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to circular construction suffers from uncertainties related to costs, market realities, supply, regulations and expertise using secondary materials in building projects. Uncertainties are large, and resolving them needs policy interventions.

From Managing Innovation to Governing Value: Reconceptualizing the Role of Intellectual Property in the Sustainable Business Model

Business Strategy and the Environment, EarlyView.
ABSTRACT The role of intellectual property (IP) in promoting or hindering sustainable innovation now forms a topical issue in innovation management. Its role in the sustainable business model remains imperfectly understood however, creating a simplified view of IP in relation to corporate sustainable development. Hence, this study sought to examine how

Self-consistent, global, neoclassical radial-electric-field calculations of electron-ion-root transitions in the W7-X stellarator

Nuclear Fusion
The radial electric field in the Wendelstein 7-X stellarator is computed by means of self-consistent, global, neoclassical simulations using the gyrokinetic particle-in-cell code EUTERPE.
