Impact of Profile Modifications and Rear View Mirror on Aerodynamics and Fuel Economy of Goods Carrier

摘要

This paper focuses on the improvements to the truck trailer aerodynamics this can be achieved by the aerodynamic drag reduction devices. The Devices are used on the truck and trailer undergone aerodynamic analysis, CFD evaluation, fuel economy assessment, these modifications provide combined fuel saving 15% at an average velocity of 30 m/s, the improvement in fuel economy correlates the equivalent drag reduction of 21%. CFD analysis shows that addition of these modification on truck trailer has no negative impact on the stability, the effect of exterior rear view mirror on the truck trailer aerodynamic drag is analysed. Result shows that modification intruck trailer geometry can reduce the drag and fuel consumption.
