Global fluid simulations of plasma turbulence in stellarators
António João Caeiro Heitor Coelho
In order to cope with the decarbonization challenge faced by many countries, fusion is one of the few alternatives to fossil fuels for the production of electricity. Two devices invented in the middle of the previous century have emerged as the most promis ...
EPFL2024Divertor turbulent transport in the single null and snowflake in the TCV tokamak
Davide Galassi, Cedric Kar-Wai Tsui, Curdin Tobias Wüthrich
The relative importance of divertor radial turbulent particle fluxes is considered by comparing it against the fluxes in the main-chamber outer midplane (OMP) in a variety of conditions and divertor geometries in the tokamak à configuration variable. Withi ...
2024Reducing transport via extreme flux-surface triangularity
Stefano Coda, Justin Richard Ball
Based on a gyrokinetic analysis of and extrapolation from TCV discharges with large negative and positive triangularity delta, the potential of extreme | delta | in reducing turbulent transport is assessed. Linearly, both positive and negative delta can ex ...
Iop Publishing Ltd2024Validation of GBS plasma turbulence simulation of the TJ-K stellarator
Paolo Ricci, Joaquim Loizu Cisquella
We present a validation of a three-dimensional, two-fluid simulation of plasma turbulence in the TJ-K stellarator, a low temperature plasma experiment ideally suited for turbulence measurements. The simulation is carried out by the GBS code, recently adapt ...
IOP Publishing Ltd2023Global fluid simulation of plasma turbulence in a stellarator with an island divertor
Paolo Ricci, Joaquim Loizu Cisquella, Maurizio Giacomin, António João Caeiro Heitor Coelho
Results of a three-dimensional, flux-driven, electrostatic, global, two-fluid turbulence simulation for a five-field period stellarator with an island divertor are presented. The numerical simulation is carried out with the GBS code, recently extended to s ...
2022Turbulent transport regimes in the tokamak boundary
The overall performance of a tokamak strongly depends on phenomena that take place in a thin region between the main plasma and the vessel wall, which is denoted as tokamak boundary. In fact, the formation of transport barriers in this region can significa ...
EPFL2022Turbulent transport regimes in the tokamak boundary and operational limits
Paolo Ricci, Maurizio Giacomin
Two-fluid, three-dimensional, flux-driven, global, electromagnetic turbulence simulations carried out by using the GBS (Global Braginskii Solver) code are used to identify the main parameters controlling turbulent transport in the tokamak boundary and to d ...

Paolo Ricci, Holger Reimerdes, Christian Gabriel Theiler, Sophie Danielle Angelica Gorno, Claudia Colandrea, Nicola Vianello, Davide Galassi, Cedric Kar-Wai Tsui, Hugo De Oliveira, Maurizio Giacomin, Eric Serre, Nicola Offeddu
Self-consistent full-size turbulent-transport simulations of the divertor and scrape-off-layer (SOL) of existing tokamaks have recently become feasible. This enables the direct comparison of turbulence simulations against experimental measurements. In this ...
IOP Publishing Ltd2022Turbulence in the scrape-off layer of double-null tokamak configurations
Understanding the turbulent dynamics in the outermost region of the tokamak is essential to predict and control the heat and particle loads to the vessel wall, a crucial problem for the entire fusion program. In this thesis, the problem is approached via t ...
EPFL2021First global simulations of plasma turbulence in a stellarator with an island divertor
Paolo Ricci, Joaquim Loizu Cisquella, António João Caeiro Heitor Coelho
We present the results of 3D, flux-driven, global, two-fluid electrostatic turbulence simulations in a 5-field period stellarator with an island divertor. The numerical simulations are carried out with the GBS code, which solves the two-fluid drift-reduced ...
