The Exhaust-Gas Recirculation (EGR) is the effective method to reduce the exhausted NOx from diesel engine. The EGR system needs to be cooled to lower the combustion temperature, which results in the reduced engine power. To improve the performance of EGR Cooler, maximizing heat transfer coefficient, heat transfer area and corrosion resistant material should be considered while the thermal stress produced by the temperature difference between exhaust gas and coolant is also considered as a highly important factor from the point of safety operation. The thermo-flow characteristics inside the EGR Cooler and surface temperature have been investigated by using CFD code STAR-CCM+ 9.0. Finally, as a result of the simulation, the stress location and crack spots has been experimentally observed and compared with simulation. The focus is going to be mainly on CFD simulation and flow behavior inside the EGR which is considered important in order to improve the efficiency.
