20.500.12556/RUL-72155 Vpliv metode za določanje vetrnih valov na emulzifikacijo razlite nafte diplomska naloga Impact of different wave parameterisation methods on oil spills V diplomski nalogi je opisan proces emulzifikacije razlite nafte. Za simulacijo le – tega se uporabljajo numerični modeli. V nalogi smo uporabili model EMU, ki je preprost program za določanje stabilnosti emulzije ter časa procesa emulzifikacije. Originalni model EMU vsebuje za določanje višine valovanja samo metodo Bretschneider. Ker slednja preceni višino valovanja, smo model nadgradili s štirimi dodatnimi metodami za določanje višine valovanja: metoda Seck – Hong, metoda CEM ter SMB metodi za globoke in plitve vode. Primerjali smo med seboj rezultate uporabljenih metod za računanje višine valovanja, časa emulzifikacije nafte Cook Inlet – Granite Point za vse metode pri različnih vhodnih parametrih. Rezultate smo prikazali v tabelah in grafikonih. Sklepamo, da je izbor metode za računanje višine valovanja pomemben dejavnik pri določanju časa procesa emulzifikacije, zlasti pri razlitju lahkih vrst nafte. In the graduate thesis we described the process of emulsification of spilled oil. Numerical models are used for simulating the process. We used the EMU model, a simple program for determining the stability of emulsion and time of the emulsification processes. In the original model only the Bretschneider method was used for calculating the wave height. Since this method overestimates the wave height, the original EMU model was modified by adding four other methods for calculating the wave height: Seck – Hong method, method CEM, and SMB methods for deep and shallow water. We compared the results of all applied methods for calculating the wave height, emulsification time of Cook Inlet – Granite Point oil, performed with all methods using different input parameters. The results are presented as tables and graphs. We concluded that the choice of wind parameterization method is an important factor in determining the time of the emulsification processes, particularly when simulating spills of light oils. gradbeništvo diplomska dela UNI B-GR morje emulzifikacija stabilnost emulzije parametri valovanja empirična parametrizacija valov graduation thesis civil engineering oil spill sea emulsification stability of emulsion wave parameters empirical wave parameterisation generalized stress field approach true false false [M.
