TermoFluids: A new Parallel unstructured CFD code for the simulation of turbulent industrial problems on low cost PC Cluster

Abstract

The main features of TermoFluids are presented. It is a new unstructured and parallel objectoriented CFD code for accurate and reliable solving of industrial flows. The more relevant aspects from a parallel computing point of view, such as communication between CPUs and parallel direct and iterative algebraic solvers that allow TermoFluids to run efficiently on looselycoupled parallel computers are presented. Also, the different approaches for turbulence modelling implemented in TermoFluids (RANS, LES and hybrid LES/RANS models) are pointed out. Illustrative results of numerical simulation of industrial problems, as the thermal optimisation of the nacelle of a wind turbine, are also presented. © 2009 Springer-Verlag Berlin Heidelberg.
