Abstract:
The Ground Transportation System (GTS) is a standard heavy-duty vehicle model used in experimental aerodynamics. Altough the control of its aerodynamic performance through the manipulation of its wake has beeninvestigated in the nineties, other desirable locations for aerodynamics control are largely unknown. We show that a lateral separation bubble is present on both sides of the cabin for yaw variations between -5º and 5º. For this range of yaw angles, Dieletric-barrier discharge (DBD) plasma actuators are capable of reducing the size of the separation bubble, although more so on the leeward side than on the windward one. The actuation is also shown to have an effect on the axial force coefficient but not on the lateral force.
