Abstract: In this study, the analysis of engine room flows has been done and the coolant temperature at radiator inlet has then been predicted using a three-dimensional radiator model that includes effects of nonuniformity of air velocity distribution across a radiator. In addition, the technique of rotating reference frame was utilised for cooling fans to improve the prediction of flow rate across a radiator. Finally, this model was verified through wind tunnel tests and applied to modify the shape of front-end openings of the existing vehicle. The results show that the current engine cooling model successfully predicts the variation of engine cooling performance with the shapes of front-end openings.
