... Abstract Recent energy crisis has forced researchers to design fuel-efficient automobiles, where one of the main critical changes is to reduce aerodynamics drag created by fluid friction. At high speed, aerodynamics drag, especially the pressure drag, creates a substantial backward force...

... Abstract As indicated by previous studies, many attributes of tires have been shown to have an impact on tire aerodynamic drag. However, the way these attributes affect tire aerodynamics has not been systematically investigated to date. It is not clear which tire attributes have the most...

... 12 02 2008 The aerodynamic drag characteristics of a heavy-duty truck with two configurations, a tractor and a single trailer, and a tractor and a tandem-trailer (two trailers), have been studied. The aerodynamic drag of a truck depends on geometry, frontal area and shape...
