Abstract

Ovim radom elaborira se CFD metoda i njezina praktična primjena. CFD metoda je metoda kojom se računalno simulira utjecaj fluida na određeno tijelo. Kroz rad se razrađuje sama teorija i primjena CFD metode u praksi. Također, u radu se provelo laboratorijsko ispitivanje i sama računalna simulacija. Konkretnije, provela su se dva laboratorijska ispitivanja, direktno mjerenje pada tlaka Pitotovom cijevi i direktno mjerenje brzine strujanja termalnim manometrom. Nakon toga se provela računalna simulacija na ispitivanom segmentu uz početne uvjete koji su uzeti iz laboratorijskog ispitivanja. Na kraju rada su se rezultati dobiveni u laboratoriju i simulaciji usporedili da se vidi postoje li sličnosti ili razlike između rezultata.

Abstract (english)

The CFD method and its practical application is elaborated in this thesis. The CFD method is a method in which a computer simulates the effects of a fluid on a certain type of object. Through the thesis the theory and application of the CFD method are examined. Also, a laboratory experiment and a computer simulation are conducted. To be more specific, two laboratory experiments were conducted, a direct measurement of a drop in pressure by the Pitot tube and a direct measurement of current speed by a thermal manometer. After that, a computer simulation was made on the examined segment with the initial conditions that we got from the laboratory experiment. At the end of the thesis, the results that came form the laboratory experiment and from the computer simulation are compared to see if any similarities or differences exist.
