20.500.12556/DKUM-90711 Meritev tokovnega polja pri obtekanju modelov avtomobilov z uporabo metode piv diplomsko delo Measurement of the flow field around car models using the piv method Diplomsko delo obravnava vizualizacijo in analizo aerodinamičnih pojavov okoli modela avtomobila pri različnih hitrostih vetra s pomočjo metode PIV (Particle Image Velocimetry). Meritve so bile izvedene pri štirih hitrostih vetra: 0,5 m/s, 0,9 m/s, 1,2 m/s in 1,5 m/s. Sistem PIV, ki vključuje lasersko tehnologijo in visoko hitrostne kamere, je omogočil natančno vizualizacijo zračnih tokov in turbulentnosti okoli modela. Rezultati kažejo, da višje hitrosti vetra povzročajo večje turbulence in motnje v tokovih, kar negativno vpliva na stabilnost in zračni upor vozila. Zaključki poudarjajo pomen aerodinamične optimizacije za izboljšanje zmogljivosti in varnosti vozil. The thesis deals with the visualization and analysis of aerodynamic phenomena around a car model at different wind speeds using the Particle Image Velocimetry (PIV) method. Measurements were conducted at four wind speeds: 0.5 m/s, 0.9 m/s, 1.2 m/s, and 1.5 m/s. The PIV system, which includes laser technology and high-speed cameras, enabled precise visualization of airflows and turbulence around the model. The results show that higher wind speeds cause greater turbulence and disturbances in the flow, negatively affecting the vehicle's stability and aerodynamic drag. The conclusions highlight the importance of aerodynamic optimization to improve vehicle performance and safety. aerodinamika PIV obtekanje model avtomobila aerodynamics PIV airflow car model true true false [J.
