Abstract
Ovim završnim radom objašnjene su najbitnije pojave koje nastaju uslijed nastrujavanja fluida na aero-profil. Teorija letenja, bazirana na silama uzgona i silama otpora, najbolje je objašnjena u teoretskom dijelu optjecanja profila preko jednadžbi. Uvođenje bezdimenzijskih koeficijenata i pojednostavljivanje neprimjenjivih jednadžbi tih sila u praksi, također je obuhvaćeno ovim radom. Ukratko je obrazloženo djelovanje hrapavosti površina na pojavu tih sila i provedena je analiza pri različitim vrstama nastrujavanja, od kojih je naglasak bio na turbulentnom strujanju fluida. Pojava separacije i vrtloga također se pojašnjava u radu. Nabrojani su karakteristični dijelovi aero-profila, a na primjeru NACA 1410 objašnjen je sam numerički zapis četveroznamenkastih NACA profila. Zadnji dio rada obuhvaća izradu simulacije nastrujavanja oko zadanog profila uz popratne grafove i detaljniju analizu tlakova i brzina, te kutova nastrujavanja.
Abstract (english)
This final paper explains the most important phenomena that occur, due to the flow of fluid to the airfoil. The theory of flight, which is based on lift and drag forces is best explained in the theoretical part through airflow equations. This paper also covers introduction to the nondimensional coefficients and the simplification of the inapplicable equations of these forces in practice. The effect of surface roughness on the occurrence of these forces is briefly explained and the analysis was performed at different types of flows, of which the emphasis was on turbulent fluid flow. The definition of separation and vortex is also explained in this paper. Characteristic parts of the airfoil with the numerical notation of four-digit NACA profiles are explained on the example of NACA 1410 airfoil. The last part of the paper includes the creation of a flow simulation around a given profile with accompanying graphs and detailed analysis of pressures and velocities, considering angle of attack.
