In this study, a three-dimensional Navier—Stokes solver was developed based on the finite volume fluid-in-cell (FVFLIC) method. The objective was to develop a comprehensive engine simulation tool that could predict unsteady flow features in the engine manifold and gas dynamic interaction between the intake system and the engine. Therefore the geometry effect of the manifold on gas dynamics could be fully investigated and later utilized in manifold design. Being shown here are some of the latest results of the research work aiming to validate the simulation program and apply it to the analysis of gas dynamics in manifolds for future design purposes.
