<p>A device to manipulate a fluid flow around a towed vehicle 200 comprises a deflecting member 300 and an attachment portion. The attachment portion is configured to attach the deflecting member proximate a front side edge 212/214 of the towed vehicle. The deflecting member is configured to control flow around the front side edge of the vehicle, such that a wake extending from the side of the vehicle is reduced. The flow may be delayed in separating from the side of the vehicle. The device may be integral or removable from the vehicle, and may be designed to extend around a portion of the front side edge of the vehicle. The device may be in the shape of a tear drop aerofoil. There may be a gap of between 2-30cm between the device and the towed vehicle, defining a duct with an inlet and outlet, wherein the inlet may be 20%-50% larger than the outlet. There may be another device positioned on the same front side edge of the towed vehicle. The towed vehicle may be a caravan.</p> |
