DPF 입구형상 변화에 따른 정상상태시 유동특성에 대한 해석

There're a lot of computational predictions in the diesel exhaust system carried out for the improvement of the flow distributions and pressure drop. Especially, in order to cope with the severe emission like EU-5 in the future. it is necessary to improve flow pattern of the new type of DPF which was installed at the end of the turbocharger directly. This study is concerned with the introduction of the swirl-type inlet parts and the investigation of swirl effect on flow pattern of the catalyst and filter under the steady state using Star-CD.
