Aerodynamic Performance of Vehicles in Platoons: The Influence of Backlight Angles 2007-01-1547
Future generation road networks are intended to feature improved throughput and significantly reduced fleet energy consumption. ‘Platooning’ arranges moving vehicles in close longitudinal convoy, and is viewed as a core aspect of such technologies.
The aerodynamic performance of platoons potentially allows increased traffic throughput and a useful energy reduction; however the magnitude of this reduction varies significantly with inter-vehicle spacing. For some vehicles in platoons under specific conditions, the resulting aerodynamic performance may actually worsen .
This work attempts to deconstruct relationships between two key vehicle geometries and their aerodynamic performance in platoons. A study of homogeneous and heterogeneous platoons using common reference models is presented.
