엔진 흡기시스템내 3차원 유동에 관한 수치연구 = Numerical Study of Three Dimensional Flow in Engine Intake System

다국어 초록 (Multilingual Abstract)

The importance of intake system can not be overstressed in the recent heavy duty commercial vehicle design. The basic requirements of intake system are to have less flow resistance and better air cleaning performance which have direct effects on the performance and service life of engine. In order to improve the performance of engine intake system, the flow phenomena in the intake system should be fullly understood. With readilly availble CFD code. the numerical analysis becomes the more reliable tools for flow optimization in recent design work.<br/>
In this research. flow field in the intake system was analyzed by Star-CD, the 3-D computaional fluid dynamic code. Especially, the flow inside of air cleaner was thoroughly analyzed. Pressure distribution and velocity profile in the air cleaner and intake duct was obtained. Having the dust seperated from incoming air at the expence of less pressure- drop is the ultimate goal for the research.<br/>
