The last decade has seen an exponential interest in conventional and unconventional energy issues. This trend has also extended to road transport issues and is driven by expectations to minimize fuel and/or energy consumption and negative environmental impact. In the global literature, much attention is focused on the work of autonomous transport, both passenger and trucks, and on the phenomena of platooning. The paper presents original aerodynamic and aeroacoustic tests of heterogeneous vehicle columns. In the work, models of a car, a van and a truck were built, followed by heterogeneous columns with different distances between the vehicles. Computational fluid dynamics (CFD) methods and two turbulence models, k−ω shear stress transport (SST) and large eddy simulation (LES), were used in this study. The study enabled the determination of drag coefficients and lift force. Application of the Ffowcs Williams–Hawkings (FW-H) analogy allowed for the determination of the distributions of sound pressure levels generated by moving vehicles and columns of vehicles. In order to verify the developed models, acoustic field measurements were made for the following passages: passenger car, van, and truck. Acoustic pressure level and A-weighted sound level (SPL) were measured in Krakow and in its vicinity. Research has shown that grouping vehicles into optimal columns and maintaining distances between vehicles using modern control systems can result in significant energy savings and reduce harmful emissions to the environment.

“…It is expected that the roads will be filled with heterogeneous traffic flows consisting of ICVs and HVs over a long period of time in the future , which will ensure the efficiency of road traffic and the reduction of overall vehicle energy consumption [4][5][6][7]. When vehicles travel close enough together, the aerodynamic drag of the follow-on vehicle will be reduced [8,9]. Therefore, for heterogeneous traffic flows, it is very significant to secure platoon stability in complex communication environments, which is crucial to ensuring safety and traffic efficiency [10][11][12][13][14].…”

“…Since the inter-vehicle distance is reduced, the rear vehicle that is following the lead vehicle can enter into the wake area of the front vehicle. As such, the interacted flow fields between two adjacent vehicles can potentially bring down the drag force [13,14]. In this paper, the effect of vehicle arrangement on the aerodynamic resistance is numerically investigated.…”

The cause of drag force vehicle accounts high fuel losses. Fuel consumption is adversely affected due to aerodynamic forces, which specially is the drag force. Vehicles that are moving in certain arrangement allows for a significant decrease in fuel consumption at highway speeds by reducing the aerodynamic drag on the moving vehicles. In this paper, the effect of vehicle arrangement on the aerodynamic resistance was numerically investigated. The vehicle models were arranged back-to-back with difference distances between each other. The distance was varied with 1.5 m, 2.0 m and 2.5 m. Computational Fluid Dynamics (CFD) was performed using ANSYS-Fluent software. The results in terms of drag coefficient were obtained for each of distance setting. There are nine different arrangements were studied. It was found out that the lowest average drag force of which 0.1857 experienced by vehicle model that are arranged at the distance of 1.5m and 2.5 m. This average drag coefficient shows a reduction of 26.8%. Consequently, the aerodynamics resistance can be significantly reduced by having a proper arrangement of vehicle cruising in highways.
