Investigating the aerodynamic reduction of drag in heavy vehicles, such as trucks or tractor-
trailers, has considerable significance given the strong influence on related industries. The …

A two-truck platoon based on a prototype cooperative adaptive cruise control (CACC)
system was tested on a closed test track in a variety of realistic traffic and transient operating …

A wind-tunnel study was undertaken to investigate the drag reduction potential of two-truck
platooning, in the context of understanding some of the factors that may influence the …

Fuel savings from truck platooning are generally attrib-uted to an aerodynamic drag-
reduction phenomena associated with close-proximity driving. The current paper is the third …

Natural wind, roadside obstacles, terrain roughness, and traffic influence the incident flow of
a vehicle driven on public roads. These transient on-road conditions differ from the idealized …

A simulation methodology is introduced to provide improved estimates of the true efficiency
gains that can be achieved using aerodynamic drag-reduction technologies for ground …

Road vehicles have been shown to experience measurable changes in aerodynamic
performance when travelling in everyday safe-distance driving conditions, with a major …

In recent investigations of the unsteadiness of flow separation, time-resolved whole-field
information, such as the temporal variation of reverse flow area and proper orthogonal …

Negative drag coefficients are normally associated with a vessel outfitted with a sail to
extract energy from the wind and propel the vehicle forward. Therefore, the notion of a heavy …

This paper describes an investigation of the performance potential of conventional flat-panel
boat-tail concepts applied to tractor-trailer combinations. The study makes use of data from …
