Abstract

The effects of exhaust gas recirculation (ECR) on smoke emissions in heavy duty diesel engine are numerically studied by using KIVA-3V CFD code. For the analysis, RNG k-$\varepsilon$ turbulence model was given as a governing equation, and mathematical models of Tab, Wave, Watkins-Park, Nagle-Strikland were applied to describe physical process of droplet breakup, atomization, wall impingement and smoke respectively.

대형디젤 기관에서 매연배기가스에 대한 배기가스 재순환장치의 영향을 KIVA-3V 전산유체해석코드를 통해서 수치 해석적으로 연구했다. 지배방정식으로 RNG k-$\varepsilon$ 난류 모델을 이용했고, 무화, 벽 침투 그리고 매연 등의 물리적인 현상을 나타내기 위해서 TAB, Wave, Watkins-Park, Nagle-Strickland 모델이 적용되었다.
