Summary:

Baseline wind tunnel programs have been conducted to develop the capability of determining vehicle front-end aerodynamic effects on engine cooling system airflow.Traditionally, the determination of these types of airflow effects has been difficult to obtain due to the upward and outward curvature characteristics of the capture stream tube ahead of the grille, as well as the turbulent characteristics of the expanding airflow directly behind the grille and bumper.A testing technique, utilizing a rake of multiple vane-anemometers, was developed to determine the total airflow and airflow distribution. This technique provided excellent results and it was determined that it was possible to quantify the total airflow and distribution as effected by various front-end, flow area components. The effect of the bumper, grille, air dam, fan and shroud were clearly discernible
