Abstract

An intake port design support tool using a CFD (Computational Fluid Dynamics) software based around the PCC (Partial Cells in Cartesian coordinate) computational mesh method was applied during the development of a motorcycle engine. The CFD analyses were performed with a relatively quick turn around time due to the reduced mesh generation time. To ensure the practical use of the tool, the CFD results have been validated using measurement data. Also recommendations for the mesh setup are described as well as details of the post processing improvements which have been implemented. This has confirmed the CFD software as a suitable design support tool.
