%X This research work presents a three-dimensional numerical study of the thermal and hydrodynamic behavior of turbulent
flow in a cross-flow heat exchanger called the intercooler. In this study, two 3D models of intercoolers with and without vortex generators are considered. The geometric configuration as well as the mesh of the computational domain are developed using a commercial Gambit 2.4.6 (2006) soft ware. Also the ANSYS-Fluent 6.3.26 (2006) code is used to compute the velocity, pressure, temperature, the turbulent kinetic energy *k*, and its rate of dissipation ε fields. The results showed that the performances are more improved by addition of the pairs of fins used as vortex generators (VG) than the classical intercooler. Moreover, the effect of the Reynolds number of cooling air on the intercooler effectiveness was examined. The
performances of the two 3D intercooler models using numerical simulation agrees well with those produced by the NTU method, indicating the reliability of the present numerical predictions.
