A Parallel, Unstructured-Mesh Methodology for Device-Scale Combustion Calculations

摘要

Los Alamos National Laboratories is developing a parallel, unstructured-mesh, finite-volume CFD methodology for the simulation of chemically reactive flows in complex geometries. The methodology is embodied in the Chad (Computational Hydrodynamics for Advanced Design) code. In this report we give an overview of the Chad numerical methodology and present parallel scaling results for calculations of flows in a four-valve Diesel engine.
