(promotor) Faculty Aerospace Engineering Department Flight Performance and Propulsion Date 2012-05-11 Abstract Low drag bluff road vehicle design can be obtained effectively and efficiently with a three phase approach that uses numerical simulations, scaled wind tunnel experiments and full-scale road testing. By applying this generalised method, SideWings were developed for an improved trailer underbody flow and tails for the trailer's rear-end. A combination of these aerodynamic devices resulted in fuel savings of up to 3 l/100 km. Further improvements could be obtained by an integral vehicle design when the front of the bluff body is redesigned as well. Although front adjustments of a bluff body are less effective, they have an influence on the drag reduction of rear-end devices, which are necessary to aerodynamically improve bluff bodies.
