A Study on Aerodynamic Drag of Semi Trailer Truck with Different Rear Height

Nowadays, with increased traffic of transport operations, fuel consumption and environmental impacts are becoming more important on heavy duty vehicles. This situation have leaded to many researches. In this study, the aerodynamic drag of a semi-trailer truck with a reduced rear height according to the standard are compared and investigated. To measure the aerodynamic drag produced by the semi-trailer trucks, computational fluid dynamics (CFD) analysis study was undertaken using a 1/1 scale 3D model trucks. Ansys Fluent software has been used to analyze flow equations and to obtain the visual outputs. The results were compared taking into account the payload volume and drag coefficient and in a scenario which internal volume is not important, it was observed that vehicle aerodynamic drag may decrease by up to 9.1% and resulting in a 4.7% improvement in fuel consumption.

Anahtar Kelimeler: semi-trailer truck, aerodynamic, rear height, CFD, drag coefficient, Fluent®
