Abstract
The heat transfer characteristics of a spiral type EGR cooler for a diesel engine are numericallyanalyzed to investigate the performance of EGR cooler. The commercial code FLUENT is utilized tosimulate a single spiral tube with constant wall temperature conditions. The numerical analysis isperformed with the variation of exhaust gas flow rate. The results show that as mass flow rate increases,temperature difference between inlet and outlet and efficiency become lower, while heat flux gets higher.
The empirical correlation is derived in forms of Nusslet number and Reynolds number based on thenumerical results.
