Abstract
The aim is to develop a theory to describe the aerodynamic behavior of active
grille shutters (AGS). The theory correlates the cooling air mass flow and drag
of a vehicle with the angle and number of air flaps on the AGS. The relatively
simple mathematical formulation of this theory provides an insight into the
aerodynamic behavior and characteristic curve shape of AGS. It illustrates how
the number of air flaps changes and influences the shape of the AGS
characteristic curve. The theory is validated by experiments using wind tunnel
measurements on real vehicles with AGS. The comparisons show good agreement
between theory and experiment.
