Una formulación numérica general para el cálculo y diseño de tomas de tierra en grandes instalaciones eléctricas
(Universitat Politècnica de Catalunya, 1997)
[Resumen] La puesta a tierra de una instalación eléctrica es imprescindible para garantizar su seguridad
cuando tienen lugar situaciones de fallo. Para su correcto análisis y diseño se requiere
la determinación de una ...
Una formulación numérica sin malla basada en los métodos SPH con ponderación de Galerkin
(Universitat Politècnica de Catalunya, 2005)
[Resumen] En este artículo se propone una formulación numérica sin malla de tipo Galerkin basada en el método de partículas SPH con aproximación de mínimos cuadrados móviles y su aplicación a problemas de mecánica de fluidos ...
High order finite volume schemes on unstructured grids using Moving Least Squares reconstruction. Application to shallow water dynamics
(John Wiley and Sons, 2005)
[Abstract] This paper introduces the use of Moving Least Squares (MLS) approximations for the development
of high-order finite volume discretizations on unstructured grids. The field variables and their
succesive derivatives ...
A generalized statement for advective-diffusive phenomena. Finite element model and applications
(John Wiley and Sons, 2000)
[Abstract] Solving convective-diffusive transport problems is a frequent task in engineering, especially in
convection dominated situations. Moreover, the standard statement for the transport problem leads to
the result ...
Why do computer methods for grounding analysis produce anomalous results?
(IEEE Power Engineering Society, 2003)
[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments and continuity of power
supply. Hence, engineers must compute the equivalent resistance of the system and the potential ...
Finite volume solvers and moving least-squares approximations for the compressible Navier-Stokes equations on unstructured grids
(Elsevier, 2005)
[Abstract] This paper introduces the use of Moving Least-Squares (MLS) approximations for
the development of high order upwind schemes on unstructured grids, applied to
the numerical solution of the compressible Navier-Stokes ...
Analysis of transferred earth potentials in grounding systems: a BEM numerical approach
(IEEE Power Engineering Society, 2003)
[Abstract] In this work we present a numerical formulation for the analysis of a common problem in electrical engineering
practice, that is, the existence of transferred earth potentials
in a grounding installation [1]. ...
Topology optimization of structures: a minimum weight approach with stress constraints
(Elsevier, 2004)
Sizing and shape structural optimization problems are normally stated in terms of
a minimum weight approach with constraints that limit the maximum allowable
stresses and displacements.
However, topology structural ...
Boundary element formulation for the analysis of transferred potentials in electrical installations
(Elsevier, 2004)
[Abstract] In this work we present a BEM numerical formulation for the analysis of a common problem in electrical engineering practice, that is, the existence of transferred earth potentials in a grounding installation ...
A boundary element numerical approach for earthing grid computation
(Elsevier, 1999)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, as well as distribution of potentials on the earth
surface due to fault currents [1,2]. While very ...
