확대관 형상에 따른 DPF 내의 유동특성 해석
Numerical study on the Air Flow Characteristics inside a DPF with Diffuser Shape
- 발행 : 2005.12.01
초록
Numerical analysis has been conducted for improving air flow characteristics in the exhaust aftertreatment system of diesel-fueled passenger cars by changing axial length and cone shape of a DPF diffuser. The results of air velocity and static pressure distributions along with air flow uniformity results suggest that a diffuser shape with 2D or 3D function type is better for air flow patterns in front of a DPF.
