Due to the stringent emission regulations for environmental protection, Exhaust Gas Regulation (EGR) system is one of the strongest candidate for de-NOx in exhaust gas at a low cost compared to LNT, DOC. Mainly EGR System are consisted of EGR Valve to control the amount of EGR and EGR Cooler to cool the exhaust gas. In case Cooled EGR has been widely using to increase charging air density and lead to be low fuel consumption. Therefore higher performance and smaller size for the EGR Cooler is required to align with smaller engine size by using turbocharger in both Diesel and Gasoline applications.
In this paper, The study for heat transfer characteristics of 5 different types of fin in EGR Cooler using in manufactured parts has been conducted. Performances were evaluated through a computational fluid dynamics (CFD) within a given same volume. Heat transfer and pressure drop were evaluated. Also engineering material cost for 5 different types of fin were estimated relatively based on using stainless steel. Finally, to optimize fin design parameter of wavy was conducted through Design of Experimental(DOE) by using orthogonal array and L16 table. From the physical test, optimized design for pressure drop at gas side had less drop compared to manufactured part and also confirmed the optimized design parameters compared to physical test showing in a 5% error rate
