Abstract Share this page

Multi-dimensional modelling of the flow and combustion promises to become a useful optimisation tool for IC engine design. Currently, the total simulation time for an engine cycle is measured in weeks to months, thus preventing the routine use of CFD in the design process. Here, we shall describe three tools aimed at reducing the simulation time to less than a week. The rapid templatebased mesher produces the computational mesh within 1-2 days. The parallel flow solver STAR-CD performs the flow simulation on a similar time-scale. The package is completed with COVISE MP , a parallel post-processor which allows real-time interaction with the data. INTRODUCTION Currently, the design of Internal Combustion (IC) engines relies mainly on experimental methods, where engine prototypes are constructed and tested in a range of operating regimes. A substantial amount of accumulated knowledge allows the engineer to meet the stringent demands on performance, emissions and fuel economy
