Neoclassical transport in quasi-axially symmetric stellarators [PDF]

, 1997
The author presents a numerical and analytic assessment of the transport in two quasi-axially symmetric stellarators, including one variant of the MHH2 class of such devices, and a configuration they refer to as NHH2, closely related to MHH2. Monte Carlo

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.

Non-Local Simulation of the Formation of Neoclassical Ambipolar Electric Field in Non-Axisymmetric Configurations

, 2005
Neoclassical transport simulation code (FORTEC-3D) applicable to non-axisymmetric configurations is developed. A new hybrid simulation model in which ion transport is solved by using the δ f Monte-Carlo method including the finite-orbit-width effects ...

Neoclassical transport coefficients for tokamaks with bean-shaped flux surfaces [PDF]

, 1990
Simple analytic representations of the neoclassical transport coefficients for indented flux surfaces are presented. It is shown that a transport coefficient for an indented flux surface can be expressed in terms of a linear combination of the previously

Quantitative comparison of impurity transport in turbulence reduced and enhanced scenarios at Wendelstein 7-X

Nuclear Fusion, 2023
We assess the turbulent particle transport being responsible for the limitation of the confinement and, thus, the overall performance of the neoclassically optimized stellarator Wendelstein 7-X.

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.

Prosumers and Sustainable Market Governance: Development of the Community‐Oriented Marketing Approach Scale

Business Strategy and the Environment, EarlyView.
ABSTRACT This research develops and empirically validates the Community‐Oriented Marketing Approach (COMA), a 20‐item multidimensional scale designed to measure prosumer perceptions within participatory market systems. COMA conceptualizes prosumers as active co‐value creators and institutional agents, driving sustainable market governance.

Evaluation of neoclassical transport in nearly quasi-isodynamic stellarator magnetic fields using MONKES

Nuclear Fusion
Stellarator magnetic fields that are perfectly optimized for neoclassical transport (with levels of radial neoclassical transport comparable to tokamaks) are called omnigenous.
