Summary:

AbstractSteady induction port flow has been simulated in a complex configuration, which is modelled on a four-valve engine with a pent-roof chamber. The numerical solution has been obtained using a finite volume method coupled with the standard k - ε turbulence model.It is shown that the 3D flow field is characterised by large vortices with horizontal axes induced by the inlet jets, and by flow interaction between inlet jets from both valves. Special attention has been paid to flow distributions in the valve curtain areas. Velocity and turbulence energy profiles have been obtained in these areas and compared with previous hot-wire measurements and 2D calculations using Reynolds stress models as well as the k - ε model. The findings in this study are expected to enhance our understanding of complex engine induction port flows and to provide better boundary conditions for in-cylinder flow calculations
