The numerical simulation of the two-dimensional turbulent flow around an automobile has been undertaken using a finite volume commercial code, STARCD. The effect of the engine compartment and the radiator has been illustrated for a vehicle travelling at 72 km/hr. The underhood flow has a strong effect on the air flowing underneath the vehicle. This effect has largely dissipated as the air leaves the rear of the vehicle. The porous radiator alters the flow significantly because of the resistance it offers to the flow. The pressure beneath the engine decreases when the radiator is present. This work demonstrates that STARCD is capable of simulating the external flow over a road vehicle and provides useful information for aerodynamic design considerations.
