Improving the aerodynamic performance of a heavy vehicles is one of the essential issues used in automotive industry to reduce the fuel consumption. In this work, various drag reduction devices were added to improve the vehicle profiles and the effects of each device were experimentally and computationally investigated. These additional devices are Cap of truck with different angle, Gap device with different length and Flat Flap with different angle and dimensions. 1/50th scale of a standard heavy truck were taken to construct the computational and experimental model. The drag coefficient, contours of turbulence kinetic energy, pressure, velocity, streamlines, velocity vectors were predicted with and without additional devices. The obtained results show that these attached devices have a notable impact on the aerodynamic drag reduction of the heavy vehicles and trucks. Installing all supplementary parts at the same time help to reduce the drag coefficient by about 59 % compared with the truck without any profile’s modifications. Finally, the experimental results show good agreement with the computational results with acceptable percentage error of about 5%.
