Abstract
U prvome dijelu diplomskog rada se teorijski opisalo uzroke i vrste onečišćenja vode te posljedice samog onečišćenja. Slijedio je pregled teorijskih osnova mehanike i dinamike fluida te je opisano područje računalne dinamike fluida. Prikazan je i detaljno opisan način dobivanja podataka iz ROMS numeričkih modela. Obrada i modifikacija istih je odrađena u pythonu. Geometrija je pripremljena pomoću SpaceClaim programa, a umrežavanje je provedeno u ANSYS Mesh-u. Pripremljeni podaci iz pythona su poslužili za postavljanje OpenFOAM slučajeva koji opisuju ulijevanje rijeke Rječine u Riječki zaljev. Simulirano je strujanje s tri različita protoka za jedan zimski i jedan ljetni dan što znači da je ukupno provedeno šest simulacija. Modelirano je širenje pasivnog skalara iz korita rijeke. Vizualizacija rezultata je odrađena u programu ParaView te su na posljetku oni uspoređeni i analizirani.
Abstract (english)
In the first part of the thesis, the causes and types of water pollution and the consequences of the pollution itself were theoretically described. This was followed by an overview of the theoretical foundations of fluid mechanics, fluid dynamics, and the field of computational fluid dynamics (CFD) was described. The method of obtaining data from ROMS numerical models is presented and described in detail. The processing and modification of the same was done in python. The geometry was prepared using the SpaceClaim, and the meshing was performed in ANSYS Mesh. The prepared data from python was used to set up OpenFOAM cases that describe the flow of the Rječina River into the Rijeka Bay. The flow was simulated with three different volume flows for one winter and one summer day, which means that a total of six simulations were performed. The propagation of a passive scalar from the riverbed is modeled. The visualization of the results was done in the ParaView. The results were compared and analyzed at the end.
