In 2D (axisymmetry) we can use nonlinear MHD codes to accurately model the position, shape control, and current control feedback systems in tokamaks, and these codes are routinely

May 19, 2022 · Implemented into the well-known SolEdge3X suite of codes (new release of SolEdge2D-EIRENE), SolEdge3X-HDG currently allows to perform accurate 2D fluid transport simulations for versatile magnetic equilibrium and tokamak wall geometries.

Mar 20, 2014 · Time-dependent transport of both plasma and neutrals is simulated during supersonic molecular beam injection (SMBI) yielding the evolution of edge plasma and neutral profiles. The SMBI model is included as a module, called trans-neut, within the original BOUT++ boundary plasma turbulence code.

May 19, 2022 · Using a simple model for erosion, present results assess the tungsten sputtering due to deuterium ions during the start-up and ramp-up phases of the discharge and confirm the need to consider full discharge simulation to accurately treat the W source of contamination.

Oct 1, 2013 · This paper presents evaluation of applicability of 2D iron core model for highly non-axisymmetric two limb configuration of GOLEM tokamak (former CASTOR). Presented results explain the long-term discrepancy between measured magnitudes of external poloidal field and those calculated by air-core approach on this tokamak.

Dec 1, 2024 · Handling plasma power deposition in the scrape-off layer (SOL) of a tokamak device is one of the most critical challenges to overcome in fusion research. In future fusion power plants such as those based on a tokamak design, the amount of power that needs to be deposited on target plates in the SOL can be more than 100 MW .

In particular this work aims to implement the Hasegawa-Mima (HME), Terry-Horton (THE) and modified Terry-Horton equations (MTHE) using pseudo-spectral methods to model turbulence in a 2D vertical slice of a tokamak.

Mar 1, 1978 · The equations describing the diffusion time scale evolution of a tokamak separate into two types, a 2D elliptic equation and a set of 1D parabolic equations. The equations are coupled in that the 1D set provides the inhomogeneous source for the 2D equation, while the 2D equation provides both the source and the geometry for the 1D set.

This project seeks to apply a reduced-kinetic parallel transport model in an existing large-scale 2D SOL code, to study reactor-relevant plasma conditions. The SNB model, implemented in the BOUT++ framework, will be applied to calculate the parallel thermal transport in …

In this paper, global structure of linearly polarized EMIC waves is examined and the result shows such resonant wave modes can be localized near the equatorial plane. We also adopt the FW2D code to tokamak geometry and examine radio frequency …
