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 ... -

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 ... -
