Abstract
The application of the LES turbulence modeling approach in the Kiva-environment is validated on a complex geometry. Results for the steady flow in a realistic geometry of a production type heavy-duty diesel engine head with 120 mm cylinder bore are presented. The bulk Reynolds number is Reb = 1 fl 105. The fluid dynamics reveals the characteristic features, such as the recirculation area below the valve, a strong local jet emerging from between the two inlet valves. The mean flow structures and its statistics are compared with PIV measurements. Best results
are achieved when applying a non-homogeneous subgrid model. The inflow conditions at the valves are crucial in reproducing correct statistics.
