Abstract

Presently exhaust emission regulation for automobile engines are being too much strengthened worldwide. In order to comply with modern pollution control norms exhaust gas recirculation (EGR) system is recognized as one of most potential techniques to reduce NOx. EGR cooler is one of the important components in EGR system. This study represents the methodology to optimize EGR cooler based on numerical techniques using computational fluid dynamics (CFD) tools. The EGR cooler performance highly depends on the design, shape and size of the cooler tubes and diffuser. By optimizing the size and the shape of the diffuser it is possible to increase the effectiveness of the EGR cooler. The flow and the heat distribution will be analyzed for the optimized geometry of the EGR cooler. The pre-processing work and post processing is carried out using STAR CCM+. The governing equations conservation of mass, momentum and energy are solved.
