Abstract

An intake port for Range Extender engine has been developed using CFD technique. Three dimensional intake port model has been built and computational analysis has been performed. Computed non-dimensional flow coefficient, swirl ratio and swirl number have been compared with the experimental result. Convex and concave curvature of the intake port have been optimized to reduce recirculation flow and flow resistance. Finally, the mean flow coefficient is 0.383 and the mean swirl number is 1.544. The intake port shows relatively excellent performance compared with those of general 2 valve engine system intake ports.

본 논문에서는 RE엔진에 적용하기위한 흡기포트를 CFD 기술을 활용하여 개발하였다. 3차원 모델링을 진행하고 전산유체해석을 진행하였으며, 계산된 유량계수와 스월계수를 실험결과와 비교 분석하였다. 흡기포트의 convex 및 concave부 곡률을 최적화하여 Recirculation의 발생과 유동저항을 저감하였다. 결과적으로, 계산된 평균 유량계수는 0.383이고, 평균 스월수는 1.544로 일반적인 2밸브 엔진 시스템의 평균성능에 상회하는 우수한 성능을 나타내었다.
