- Abstract
To find out and improve the flow characteristics inside the intake system of cylinder head, the application of computational fluid dynamics ( CFD) in the evaluation and optimization of the reconstructed intake system based on slicing reverse method was proposed. The flow characteristics were found out through CFD, and the velocity vector field, pressure field and turbulent kinetic energy field for different valve lifts were discussed, which were in good agreement with experimental data, and the quality of reconstruction was evaluated. In order to improve its flow characteristic, an optimization plan was proposed. The results show that the flow characteristics after optimization are obviously improved. The results can provide a reference for the design and optimization of the intake system of cylinder head.
