Moving Mesh를 이용한 PCV 밸브의 내부유동 수치해석 = A numerical analysis for internal fluid flow of a PCV valve by using moving mesh

다국어 초록 (Multilingual Abstract)

A great deal of exhaust gas inside a combustion Toom goes out through exhaust pipe but residual gas, is called "Blow by gas", enters the crankcase through a small gap between the piston and the cylinder wall. Here, if the crankcase isn't vented, thjs causes many bad effects such as lubricant oil contamination, corrosion by that and crankcase explosion by rising pressure. So most automobiles are constituted with a PCV(Positive Crankcase Ventilation) system to prevent previous problems. PCV valve is the most important part in this ventilation system. When companies are manufacturing new cases, engineers are designing it depending on their experiments than theoretical knowledges. Much efforts and times are needed for new development, This study will show quantitative results to increase the possibilities.
