A COMPUTER MODEL FOR POROUS FLOW IN UNDERGROUND SYSTEMS

UN MODELO COMPUTACIONAL PARA FLUJO POROSO EN SYSTEMAS SUBTERRÁNEOS
PhD. Naghmeh Keshavarzi-Roonizi.

Abstrac: In this paper a 3-D computer model for the quantitative analysis of underground flow is presented. This generic model can be applied to simulate underground flows which, mainly are characterised by flow through porous media or combined free/porous regimes in sub-surface regions. This paper covers the extension of this model to combined flow systems as well as flow through unsaturated domains where the advancing flow front needs to be tracked. In order to make the software accessible for the novice user, the incorporation of the present model into a previously developed computer network system is described.

Resumen: En este artículo se presenta un modelo computacional en tercera dimensión para el análisis cuantitativo de flujos subterráneos. Este modelo genérico puede ser aplicado para simular flujos subterráneos, los cuales se caracterizan principalmente por que pasan a través de medios porosos o regímenes combinados libre/poroso en regiones bajo la superficie. Este trabajo cubre la extensión de este modelo a sistemas de flujo combinado, así como también para flujos a través de dominios no saturados, donde es necesario hacer un seguimiento al flujo circulante. Para hacer este software accesible a usuarios novatos, se describe la incorporación del modelo propuesto en un sistema de red de computadores previamente desarrollado.
