Abstract
Primjenom računalne dinamike fluida i analizom dobivenih numeričkih i vizualnih rješenja odgovorilo se na pitanje kako otvoreni krovni prozor utječe na strujanje zraka, sile otpora, koeficijente otpora i druge fizikalne veličine. Nakon analize može se zaključiti da će otvaranje krovnog prozora smanjiti koeficijent otpora zraka za automobil što je povoljno, ali će radi povećanja poprečnog presjeka u ravnini koja je okomita na gibanje automobila ukupna sila izvršena na automobil u suprotnom smjeru od njegova gibanja biti veća s otvorenim prozorom. Saznalo se i da je put koji će automobil sa zatvorenim prozorom prijeći biti veći za istu količinu goriva pri putnoj brzini od 35 m/s (126 km/h), za ispitanu geometriju automobila.
Abstract (english)
By applying computer fluid dynamics and analyzing the obtained numerical and visual solutions, the question of how an open sunroof affects air flow, resistance forces, resistance coefficients and other physical quantities was answered. After the analysis, it can be concluded that opening the sunroof will reduce the air resistance coefficient of the car, which is favorable, but due to the increase in the cross-section in the plane perpendicular to the car's motion the total force exerted on the car in the opposite direction to its movement will be greater with the window open. It was also found that the distance traveled by the car with the window closed is greater for the same amount of fuel at a road speed of 35 m/s (126 km/h), for the tested geometry of the car.
