초록
This study presents 3D CFD analysis for the first version experimental rotary engine originated from 3 lobes Gerotor pump (GP3 RTE). The CONVERGE software is used for its powerful tool for automatic meshing and combustion modeling with detailed chemistry mechanism. The CFD methods are validated and flow characteristics with four strokes are clarified. The results describe the unique characteristic of the new engine well and may allow powerful tool to validate design parameters. Specifically, the EGR behavior during the intake-exhaust port overlap and the interference phenomenon during the port overlap between neighboring cylinders, unique to the engine, must be investigated thoroughly to get good performance of the engine.
