Summary:

An automatic hexahedral meshing technique has been combined with CFD to predict the steady flow through practical intake port/valve geometries. Two intake configurations were investigated. An asymmetric design consisting of one helical and one directed port and a symmetric design consisting of two directed portraits The automatic meshing technique dramatically reduces the mesh construction time to less than 15% of that achievable by the conventional route.Detailed LDA, laser sheet, and swirl measurements reveal that for certain flow conditions and port arrangements it is possible to obtain a good match between the measured and predicted in-cylinder flow structure. The best predictions of in-cylinder swirl were within 5% of the measured values. It is also shown that this approach to mesh generation is both economic and robust for practical engine designs, transforming CFD into a practical tool for the design of intake portraits
