Nonlinear simulation of plasma turbulence using a gyrokinetic moment-based approach
Plasma turbulence plays a fundamental role in determining the performances of magnetic confinement fusion devices, such as tokamaks. Advances in computer science, combined with the development of efficient physical models, have significantly improved our u ...
EPFL2024A Gyrokinetic Moment Model of the Plasma Boundary in Fusion Devices
The overall performance of fusion devices, such as tokamaks, is strongly correlated to thephenomena that occur in the boundary region, the outer plasma region that faces the wall of the device. The boundary plays a crucial role in regulating the heat and p ...
EPFL2023Neural network surrogate of QuaLiKiz using JET experimental data to populate training space
Within integrated tokamak plasma modeling, turbulent transport codes are typically the computational bottleneck limiting their routine use outside of post-discharge analysis. Neural network (NN) surrogates have been used to accelerate these calculations wh ...
AMER INST PHYSICS2021First 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 ...
2021A semi-Lagrangian splitting method for the numerical simulation of sediment transport with free surface flows
Marco Picasso, Alexandre Caboussat, Gilles Steiner, Arwa Mrad
We present a numerical model for the simulation of 3D poly-dispersed sediment transport in a Newtonian flow with free surfaces. The physical model is based on a mixture model for multiphase flows. The Navier-Stokes equations are coupled with the transport ...
PERGAMON-ELSEVIER SCIENCE LTD2018A Drift-Kinetic Model for Tokamak SOL Plasmas
Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge
A fluid drift-reduced description, which accurately describes phenomena occurring on time scales slower than the characteristic gyro-frequencies and space scales longer than the Larmor radii, has been successfully used in recent years to model the dynamics ...

2016Geometric multiscale modeling of the cardiovascular system, between theory and practice
Alfio Quarteroni, Christian Vergara
This review paper addresses the so called geometric multiscale approach for the numerical simulation of blood flow problems, from its origin (that we can collocate in the second half of '90s) to our days. By this approach the blood fluid-dynamics in the wh ...

MATHICSE2016Parallel Algorithms for the Solution of Large-Scale Fluid-Structure Interaction Problems in Hemodynamics
This thesis addresses the development and implementation of efficient and parallel algorithms for the numerical simulation of Fluid-Structure Interaction (FSI) problems in hemodynamics. Indeed, hemodynamic conditions in large arteries are significantly aff ...
