Numerical Analysis of Aeroacoustic Phenomena Generated by Heterogeneous Column of Vehicle

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