Airflow analysis around a simplified modern car model type 2

Ovim završnim radom objašnjeni su osnovni teorijski pojmovi kod aerodinamike automobila. Na jednostavnim primjerima pokazano je opstrujavanje fluida oko automobila i fenomeni koji se javljaju prilikom opstrujavanja. U programu Ansys Fluent provedena je CFD simulacija opstrujavanja oko jednostavnog modela automobila. Simulacijom je pokazano kako fluid opstrujava oko automobila, raspored statičkog, dinamičkog i totalnog tlaka, raspored vektora brzine fluida koji struji oko automobila, mjesta pojave turbulencija, recirkulacijske zone itd. Također je objašnjeno koji se problemi javljaju prilikom strujanja fluida i zašto je potrebno da prijelazi na automobilu budu što uglađeniji.This final paper explains the basic theoretical concepts in car aerodynamics. Simple examples show the flow of fluid around a car and the phenomena that occur during the flow. In the Ansys Fluent program, a CFD simulation of the flow around a simple car model was performed. The simulation shows how fluid flows around the car, the distribution of static, dynamic and total pressure, the distribution of the fluid velocity vector flowing around the car, the places of turbulence, recirculation zones, etc. It also explains what problems occur during fluid flow and why it needs to cross on the car be as smooth as possible
