Variational multiscale stabilization for compressible flow

Description: This paper presents a variational multiscale stabilization for the finite element numerical solution of the Euler and Navier-Stokes equations of compressible flow. All the components of the dual operator are considered in the stabilization term and two options are proposed for the computation of the...

Continental contributions to coastal zone: natural and anthropogenic disturbances in biogeochemical river flows and their traceability in the sedimentary compartment

Description: 149 pages , The continental contributions of matter driven by small rivers, is a developing topic to be considered by the scientific community. This Thesis presents four already published studies focused on the Galician Rias, a coastal area dominated by small rivers inputs. Using trace elements as geoc...

Steel compression design: the bucklings weigth

Description: The verification of the slender compressed members of a structure is a well formulated and codified problem. However, the non-linearity of the design process, combined with the no linearity of the physical problem requires an iterative process to define the piece that solves a given problem. This pa...

A fractional step method for the solution of the compressible Navier-Stokes equations

Description: In this paper we present a summary of the splitting technique for both compressible and incompressible flows previously proposed in [22, 23, 7]. Also, we extend it to the case of a fully implicit treatment of the viscous and convective terms of the momentum equations. For incompressible flows, this ...

A general algorithm for compressible and incompressible flows. Part III: The semi‐implicit form

Description: In this paper we consider some particular aspects related to the semi‐implicit version of a fractional step finite element method for compressible flows that we have developed recently. The first is the imposition of boundary conditions. We show that no boundary conditions at all need to be imposed ...

A numerical model for temporal variations during explosive central vent eruptions

Description: An axisymmetrical numerical model has been developed in order to find the temporal evolution of pressure, the position of the exsolution level, the velocity field, the eruption rate, and the amount of erupted material of a shallow, volatile‐rich, felsic magma chamber during a Plinian central vent er...

Numerical modelling of compressible laminar and turbulent flow. The Cbs algorithm

Description: This work is about the development of a general algorithm for the numerical solution of flow equations: the Navier-Stokes set. This set of differential equations models the time dependent behavior of fluids. It is formed by continuity, linear momentum and an energy transport equations. The algorithm...

Extraction of data dependencies

Description: Relational database schemas must be semantically enriched to reflect knowledge about the data, as needed by many applications. One technique is the analysis of the database extension, extracting existing data dependencies. In this paper, new algorithms to extract functional and inclusion dependencie...

Fluvial transport patterns of dissolved trace metals to the Ria of Cedeira

Description: 5 páginas.-- Interdisciplinary Water Congress CINA 2014, Vigo, 2-6 June 2014 , Samples of water were withdrawn monthly close to the Das Mestas River mouth, out of the tidal influence, from October 2011 to September 2012 (covering a hydrological year). After filtration through 0.45 policarbonate membran...

Growth of sculpted forms in bedrock channels (Miño River, northwest Spain)

Description: 7 páginas, 4 tablas, 6 figuras , A total of 216 sculpted forms were registered on the granitic bedrock of the Miño River, northwest Iberian Peninsula. Analysis of in situ measurements (length, width and depth) revealed three general type-sets: incipient forms, longitudinal furrows and circular pot-ho...
