Base Drag Reduction of Heavy Duty Vehicles by Combining a Tail and Guide Vanes: A Numerical and Experimental Analysis

To limit the threat posed by global climate change it is vital to reduce the emissions of the transport sector in the short term. Two existing aerodynamic add-on devices for the rear-end of a heavy duty vehicle, a tail and guide vanes, are combined in an attempt to achieve a larger drag reduction. A research is performed using numerical...
