Impact of the underside velocity on the drag reduction of a trailer model using a passive control system

Résumé

The effect of passive control (inclined boat-tails) on the flow in the wake of a 1:43 scale simplified trailer model is experimentally studied for various underside flow conditions. Base pressure measurements show that the boat-tails allows increasing the base pressure whatever are underside flow velocities studied and the base pressure distribution is always symmetric in the vertical mid plane. In addition, according to the underside flow velocity, the near-wake flow structure consists of a recirculating area attached or completely detached from the ground.
