Abstract

This paper presents the numerical simulations of a flow around an exhaust valve, inside the cylinder of a fourstroke combustion engine. The different flow models have been tested. Besides, the impact of the dimensionality and geometry detailness has been studied. Fixed (i.e. non-moving) geometry and steady boundary conditions have been assumed for all simulations. All the results presented have been obtained by a newly developed CFD package, based on finite volume method (FVM) with an AUSM-family numerical scheme.
