The design of more efficient automotive cooling systems requires better understanding of the losses in fluid mechanical energy through conversion to thermal energy for the airflow through the front end cooling openings. A wind tunnel study with simplified models has been conducted to investigate the factors affecting the cooling opening mechanical energy losses. The data from this study have been successfully correlated using newly defined dimensionless parameters. The influence of the controlled geometrial factors are clearly identifiable with the data presented in dimensionless form. An algorithm has been devised which accurately correlates the behavior of a combination of cooling openings given the behavior of each of the openings operating individually.
