Abstract: Exhaust gas recirculation (EGR) coolers can profoundly reduce hazardous NOx emissions from Diesel engines. In this project flow and heat transfer characteristics of Full spiral shell and tube EGR cooler is investigated experimentally and numerically using CFD (ANSYS FLUENT V16.4) software. Geometrical parameters of modification of spiral corrugated tubes include diameters (inside and outside), effective length, thickness, Pitch, number of revolutions were made by constructing 5 models of EGR coolers with A-7 tubes, B-9 tubes, C-11 tubes, D-13 tubes and E-15 tubes using ANSYS FLUENT. Model D with 13 tubes is found to be efficient and economical. Using spiral corrugated tubes shown improvement in Heat transfer effectiveness and heat transfer coefficient experimentally and numerically for 13 tubes EGR Cooler. Also almost 22% increase in effectiveness is observed using spiral corrugated tubes instead of plain tubes. Both experimental and numerical results are obtained and are compared. BS-VI is a significant advancements with regard to NOx limits having 0.06 gm/km. EGR cooler with spiral corrugated tubes can help in reducing NOx limits to great extent.
