Article
Open AccessWe propose a new activity on verification and validation (V&V) of MHD codes presently employed by the fusion community as a predictive capability tool for liquid metal cooling applications, such as liquid metal blankets. ... -
Approximation of the inductionless MHD system with finite element techniques
(Universitat Politècnica de Catalunya, 2010-06-01)
Master thesis
Open AccessIn this work, a stabilized formulation to solve the inductionless magnetohydrodynamic (MHD) problem using the finite element method is presented. The important feature of this formulation resides in the design of the ... -
Basics of magnetohydrodynamics
(Universitat Politècnica de Catalunya / Nagaoka University of Technology, 2013)
Master thesis (pre-Bologna period)
Restricted access - author's decisionIn the present work the basic principles of a MHD channel are described through the development of a simulation and the interpretation of its results. The MHD channel is modeled through the Euler conservation equations for ... -
Block recursive LU preconditioners for the thermally coupled incompressible inductionless MHD problem

External research report
Open AccessThe thermally coupled incompressible inductionless magnetohydrodynamics (MHD) problem models the ow of an electrically charged fuid under the in uence of an external electromagnetic eld with thermal coupling. This system ... -
Estudi i resolució de les equacions de massa, quantitat de moviment i energia sotmeses a un camp magnètic. Identificació de possibles aplicacions
(Universitat Politècnica de Catalunya, 2014-09)
Master thesis (pre-Bologna period)
Open AccessEl projecte consisteix en l’estudi de la interacció entre la dinàmica de fluids i l’electromagnetisme, enfocada des d’un punt de vista numèric en comptes d’experimental. Per una banda, la dinàmica de fluids és una branca ... -
Experimental techniques in determination of electron cyclotron power deposition profiles in thermonuclear plasmas
(Universitat Politècnica de Catalunya / Politecnico di Milano, 2014)
Master thesis (pre-Bologna period)
Open AccessElectron cyclotron waves are widely used in magnetic confinement devices, specially in those involved in nuclear fusion research, to heat the electrons and achieve the ignition temperature. A still unsolved issue is ... -
MHD issues related to the use of Lithium Lead eutectic as breeder material for blankets of fusion power plants
(2015-04-01)
Article
Restricted access - publisher's policyThe European Community is committed to the development of a DEMOnstration fusion power plant whose operation could start as soon as 2050. The blanket is one of the most critical components in a fusion reactor; three of the ... -
Non-linear magnetohydrodynamic simulations of plasma instabilities from pellet injection in Large Helical Device plasma
(2019-08-13)
Article
Restricted access - publisher's policyThe effect of pellets on the global magnetohydrodynamic (MHD) dynamics of the Large Helical Device (LHD), which is a large superconducting heliotron in Japan, has been analyzed with the MIPS code. A pellet ablation model ... -
On an unconditionally convergent stabilized finite element approximation of resistive magnetohydrodynamics
(2013-02)
Article
Open AccessIn this work, we propose a new stabilized finite element formulation for the approximation of the resistive magnetohydrodynamics equations. The novelty of this formulation is the fact that it always converges to the physical ... -
