Recent Upgrades in a 2D Turbulent Transport Solver Based on a Hybrid Discontinuous Galerkin Method for the Simulation of Fusion Plasma in Tokamak

Autor: Giacomo Piraccini, Marcello Capasso, Manuel Scotto D’Abusco, Giorgio Giorgiani, Frédéric Schwander, Eric Serre, Hugo Bufferand, Guido Ciraolo, Patrick Tamain

Publikováno v: Fluids, Vol 7, Iss 2, p 63 (2022)

The simulation of fusion plasmas in realistic magnetic configurations and tokamak geometries still requires the development of advanced numerical algorithms owing to the complexity of the problem. In this context, we propose a Hybrid Discontinuous Ga

Tokamak Edge Plasma Turbulence Interaction with Magnetic X-Point in 3D Global Simulations

Autor: Davide Galassi, Guido Ciraolo, Patrick Tamain, Hugo Bufferand, Philippe Ghendrih, Nicolas Nace, Eric Serre

Publikováno v: Fluids, Vol 4, Iss 1, p 50 (2019)

Turbulence in the edge plasma of a tokamak is a key actor in the determination of the confinement properties. The divertor configuration seems to be beneficial for confinement, suggesting an effect on turbulence of the particular magnetic geometry in

Optimal Transient Growth in an Incompressible Flow past a Backward-Slanted Step

Autor: Marco Martins Afonso, Philippe Meliga, Eric Serre

Publikováno v: Fluids, Vol 4, Iss 1, p 33 (2019)

With the aim of providing a first step in the quest for a reduction of the aerodynamic drag on the rear-end of a car, we study the phenomena of separation and reattachment of an incompressible flow by focusing on a specific aerodynamic geometry, name
