Unsteady analysis of flow around body

U ovome radu, konstruiran je kružni i aerodinamični oblik krovnog nosača te potom je provedena simulacija opstrujavanja zraka oko profila. Izrada mreže geometrije odvija se u programu HyperMesh nakon koje slijedi simulacija u programu Virtual Wind Tunnel. Dobiveni rezultati u nastavku prate analizu i usporedbu dvaju krovnih nosača. Uspoređivanje dobivenih koeficijenata uzgona i koeficijenata otpora dovodi nas do ključne razlike između opstrujavanja zraka dvaju profila te bit aerodinamike u današnjem svijetu.In this paper, it was designed circular and aerodynamic shape of two different roof rack. Afterwards a simulation of airflow around the profile was performed. The creation of mesh geometry takes place in program HyperMesh followed by a simulation in the program Virtual Wind Tunnel. The results obtained below follow the analysis and comparison of the two roof racks. Comparing the obtained drag and lift coefficients leads us to a key difference between the air flow of the two profiles and the essence of the aerodynamics in today's world
