CFD presenta compresible + incompresible un matrimonio por conveniencia

Abstract

Este trabajo presenta por un lado una breve síntesis de algunas importantes contribuciones dirigida a la unificación de códigos computacionales para flujos tanto compresible como incompresible y por otro un eficiente precondicionador local para todo el rango de números de Mach y Reynolds implementado sobre un esquema iterativo tipo GMRES con una estrategia que evita el ensamblaje de matrices llamada matriz-free usando como discretización espacial una formulación en elementos finitos. El principal objetivo de esta investigación es lograr un tratamiento unificado de flujo de fluidos tanto compresible como incompresible, viscoso o inviscido apto para simulaciones a gran escala y capaz de ser utilizado sobre plataformas de hardware paralelas.

This paper presents a brief review of important contributions towards the unification of compressible and incompressible flow solvers and an efficient local preconditioner for al1 Mach and Reynolds numbers implemented with a matrix-free GMRES iterative scheme and a finite element method. The main goal of this research is the unified treatment of fluid flow at al1 speeds for large scale simulation capable of being implemented over parallel platforms.
