Abstract
U završnom radu “Simulacija strujanja fluida korištenjem OpenFOAM-a” je prema zadatku izrađen proračun turbulentnog toka fluida kroz rešetku čija geometrija započinje lukom na prednjom kraju, na koji se nastavljaju bridovi koji se sužavaju prema stražnjem kraju. Napravljena je numerička mreža za zadanu geometriju koja predstavlja jednu rešetku zbog simetričnosti promatranog problema. Simulacije strujanja su napravljene u programu OpenFOAM za brzine strujanja od 0,5 m/s, 1 m/s, 2 m/s i 5 m/s. Rezultati simulacije prikazani su slikama za brzinu strujanja fluida po komponentama x, y, z te statički i totalni tlak. Iz slika uočavamo gdje se nalaze najveće i najmanje brzine strujanja i tlakovi. Na kraju grafom uspoređujemo rezultate dobivene simulacijom i rezultate izračunate pomoću literature temeljene na eksperimentalnim mjerenjima, odnosno padove tlakova za svaku od brzina te iz njih uočavamo kvadratnu ovisnost.
Abstract (english)
In the final work titled " Fluid flow simulation using OpenFOAM", a task was used to make a calculation of turbulent fluid flow through the grid whose geometry starts with an arch at the first end, from which the bridges continue and keep narrowing towards the other end. A numeric mesh was built for the default geometry which represents one grid due to the symmetry of the observed problem. The flow simulations are made in OpenFOAM program for flow rates 0,5 m/s, 1 m/s, 2 m/s and 5 m/s. The results of the simulations have been shown with pictures of fluid flow rate per components x, y, z and static and total pressure. From the above said pictures we can notice where do the biggest and smallest flow rates and pressures occur. The visual presentation is concluded with a graph whose purpose was to compare the results given by simulation and the results calculated with the help of literature based on experimental activities, that is the shifts of pressures for each given flow rate from which we have successfully noticed square dependency.
