LPL EGR 사이클론 응축수 분리기의 설계 변수에 따른 해석적 연구

다국어 초록 (Multilingual Abstract)

The EGR systems are classified as HPL and LPL EGR ones depending on the supply position of the recirculated exhaust gas. Recently, LPL EGR system with high EGR rate is increasing. in order to cope with the exhaust gas regulation to be strengthened. Depending on the operating conditions of the charge air cooler and the engine, strong acidic condensate is generated inside it. Condensate causes charge air cooler corrosion and engine problems. Therefore, it is necessary to preliminarily separate the condensed water from the exhaust gas outlet of the EGR cooler. Cyclone condensate separator is a device that separates condensate from exhaust gas through rotary flow by centrifugal force. In this study, the separation performance of the cyclone condensate separator according to the cylinder diameter and cone length was compared and analyzed over for several models by CFD numerical analysis.
