SUPG stabilized finite element resolution of the Navier-Stokes equations: application to water treatment engineering
(Elsevier, 2002)
[Abstract] In this paper an analysis of the viscous incompressible flow has been carried out, from the very definition of the governing equations, up to the resolution of some practical problems, passing through the ...
A numerical formulation for grounding analysis in stratified soils
(IEEE Power Engineering Society, 2002)
[Abstract] The design of safe grounding systems in electrical installations is essential to assure the security of the persons, the protection of the equipment and the continuity of the power supply. In order to achieve ...
A particle numerical approach based on the SPH method for computational fluid Mechanics
(2004)
[Abstract] Meshfree methods have experimented an important improvement in the last decade.
Actually, we can say that the emerging meshless technology constitutes the most
promising tool to simulate complex problems in ...
On the intrinsic instability of the advective-diffusive transport
(2004)
[Abstract] A new theory for the advective–diffusive phenomenon is described in this study and the causes for the failure of the conventional numerical methods for this problem are investigated.
It is shown that Fick’s law ...
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 ...
Aplicación de una formulación de elementos finitos para la resolución del flujo en unidades de proceso de aguas residuales
(Fundación para el Fomento de la Ingeniería del Agua, 2003)
[Resumen] En el presente trabajo se exponen los resultados de la aplicación de una formulación numérica
propuesta por los autores, en la resolución de varios problemas de flujo relacionados con el tratamiento
de aguas ...
A boundary element numerical approach for substation grounding in a two layer earth structure
(Tech Science Press, 1997)
[Abstract] Analysis and design of substation grounding requires computing the distribution of potential
on the earth surface (for reasons of human security) and the equivalent resistance of the earthing
system (for reasons ...
Analytical integration techniques for earthing grid computation by boundary element methods
(Centro Internacional de Métodos Numéricos en Ingeniería, CIMNE (Barcelona), 1992)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, but also distribution of potentials on the earth surface due to fault currents [1]. While very crude ...
A validation of the boundary element method for grounding grid design and computation
(Centro Internacional de Métodos Numéricos en Ingeniería, CIMNE (Barcelona), 1992)
[Abstract] Several widespread intuitive techniques developed during the last two decades for substation grounding analysis, such as the Average Potential Method
(APM), have been recently identified as particular cases of ...
¿Son fiables los métodos convencionales para el cálculo de redes de puesta a tierra?
(2004)
[Resumen] Para diseñar una toma de tierra es preciso calcular su resistencia equivalente y la distribución de potencial en la superficie del terreno durante una derivación de corriente [1, 2, 3]. Para elllo las normas sólo ...
