Abstract
U radu se analizira pristup realnome tretiranju rubnih uvjeta na granici domene kod modeliranja strujanja mora u Riječkom zaljevu. Izloženi su razlozi za potrebom modeliranja 3D strujanja mora uz nametanje rubnih uvjeta uzimajući u obzir profil brzina po dubini. Opisane su metode mjerenja profila po dubini u svrhu prikupljanja podataka i njihov povijesni razvoj. Objašnjena je teorijska osnova mehanike fluida potrebna za modeliranje problema. Metodologija modeliranja računarskom dinamikom fluida je opisana uz osvrt na CFL uvjet. Pripremljeni su geometrijski model i numerička mreža. Predložen je način prikupljanja i organiziranja ulaznih podataka brzine po visini profila strujanja. Proučava se integracija dva seta podataka rubnih uvjeta, zadanih po visini profila brzine te po površinskom sloju mora. Opravdanost zadavanja rubnih uvjeta iz dva seta podataka ocjenjuje se u analizi rezultatima.
Abstract (english)
The paper analyzes an approach to the real treatment of boundary conditions at the domain boundary in the modeling of sea flow in the Gulf of Rijeka. The reasons for the needs of modeling 3D sea currents with the naming of boundary conditions taking into account the velocity profile by depth are presented. Methods of measuring depth profiles for the purpose of data collection and their historical development are described. The theoretical basis of fluid mechanics required for modeling the problem is explained. The computational dynamic fluid modeling methodology is described with reference to the CFL condition. A geometric model and a numerical grid were prepared. A method of collecting and organizing the velocity input data according to the height of the flow profile was proposed. The integration of two sets of boundary condition data, given by the height of the velocity profile and by the sea surface layer, is studied. The adoption of boundary condition from the two data sets is evaluated in the analyzed results.
