Extension of Spectral/hp Element Methods towards Robust Large-Eddy Simulation of Industrial Automotive Geometries

چکیده
A spectral/hp element methodology is utilised to investigate the SAE Notchback geometry with 20∘ backlight and 3∘ diffuser at Re=2.3×106. The study presented here considered two different mesh approaches: one focusing on classical h-type refinement standard solution polynomial order (HFP3) a second case considering relatively coarse combined high (HCP5). For same targeted number of degrees freedom in both meshes, results show significant differences vorticity, flow structures surface pressure. first guidelines for hp strategy are deduced complex industrial cases. Further work investigating requirements these hybrid techniques required maximize benefits refinements method simulations.

Large-eddy simulation (LES) has traditionally been restricted to fairly simple geometries. This paper discusses LES of reacting flows in geometries as complex as commercial gas turbine engine combustors. The incompressible algorithm developed by Mahesh et al. (J. Comput. Phys., 2004, 197, 215–240) is extended to the zero Mach number equations with heat release. Chemical reactions are modeled us...
متن کاملA numerical method for large-eddy simulation in complex geometries
We discuss the development of a numerical algorithm, and solver capable of performing large-eddy simulation in the very complex geometries often encountered in industrial applications. The algorithm is developed for unstructured hybrid grids, is non-dissipative, yet robust at high Reynolds numbers on highly skewed grids. Simulation results for a variety of flows are presented. 2003 Elsevier Inc...
