Aerodynamic Drag Reduction of Intercity Buses

SAE Technical Paper Series, 1980
<div class="htmlview paragraph">An experimental program was conducted to verify the reduction in fuel consumption achievable with aerodynamic improvements to intercity buses. Wind tunnel model tests were used to develop effective aerodynamic improvements and full-scale road tests to validate the results. Greyhound Lines coach models MC-7 and MC-8

Aerodynamic drag reduction of goods trains

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract Tests on one-tenth scale hopper and gondola rail cars have been undertaken in a closed-circuit wind tunnel with a fixed floor. By varying the number of wagons in the train length, it was concluded that simulation of a typical wagon away from end effects (i.e.

Prediction of Aerodynamic Drag.

1984
Abstract : Drag prediction is the most important and challenging problem in aerodynamics. Experimental, empirical, analytical and numerical approaches, singly and in concert, have addressed this problem with varying degrees of success (and notable failures).

The aerodynamic drag of grassland

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1950
An improvised drag-plate apparatus, on the principle of that used by Sheppard (1947) on a concrete surface, but suitably modified in design, has been used for exploratory measurements of the aerodynamic drag of grassland. The grass cover was variable (1 to 15 cm.

Aerodynamic Drag on Vehicles in Tunnels

Journal of Basic Engineering, 1969
The purpose of this study was to investigate the aerodynamic drag on vehicles moving in guideways of varying degrees of enclosure. The reason for this study was that several potential high speed ground transport system concepts involve high speed motion of vehicles in enclosed guideways for significant portions of their travel time.

Aerodynamic drag of mountain bike tyres

Sports Engineering, 2001
This paper proposes the concept of a front wheel air deflector for downhill mountain bikes. Downhill mountain bike tyres are becoming larger with more aggressive tread patterns in order to cope with the increasingly severe conditions of modern downhill courses, which in turn leads to increased aerodynamic drag forces caused by air flow, and ...
