Validation of CFD Analysis and Combustion Characteristics of GP3 Rotary Engine at Firing Condition

초록

This study presents 3D CFD analysis for the first version experimental rotary engine originated from three lobes Gerotor pump (GP3 RTE). The CONVERGE software is used due to its powerful tool for combustion modeling with detailed chemistry mechanism. The reduced reaction models based on GRI-Mech 3.0 full reaction mechanism are validated and reasonable ranges of target species and error tolerance are selected. The results describe well the unique characteristic of the new engine. Specifically, the information on EGR behavior during the port overlap, quenching regions, indicated power and efficiency, and emission characteristics may allow powerful tool to validate the design parameters.
