Abstract
In this study, the heat transfer characteristics of three types of EGR coolers, such as Shell and tube-type EGR cooler (6â¯mm), Shell and tube-type EGR cooler (8â¯mm), and stack type-EGR cooler, were numerically investigated. The accuracy of predictions was verified by experimental results. A maximum difference between the numerical result and the experimental result for heat transfer efficiency of 9.22% was obtained. The results showed that the heat transfer efficiency of stack type-EGR cooler is higher of 36.6% and 27.7% than Shell and tube-type EGR cooler (6â¯mm) and Shell and tube-type EGR cooler (8â¯mm) was higher respectively. The results showed by increasing the mass flow rate, the heat transfer efficiency in the stack type-EGR cooler almost remain constant. When the stack type-EGR cooler is used, the heat transfer coefficient and Nusselt number improve significantly compared to the Shell and tube-type EGR cooler (6â¯mm) and Shell and tube-type EGR cooler (8â¯mm).
