20.500.12556/RUL-32461 Vpliv prostorskega povprečenja vetra na cirkulacijo v Tržaškem zalivu diplomska naloga Impact of spatial averaging of wind on circulation in the Gulf of Trieste V diplomski nalogi smo obravnavali vpliv prostorskega povprečenja dejanskega vetra na cirkulacijo v Tržaškem zalivu. Dejanski veter, podan v resoluciji 150 x 150 m, smo povprečili prek štirikrat in na dva načina devetkrat večjih območij, za vsako uro dvainsedemdeseturne simulacije. Simulacije hidrodinamike smo izvedli z modelom PCFLOW3D ter rezultate izrisali na globini 0,5 m in 10,5 m. Zaradi majhnih razlik med slikami hitrostnih polj tokov smo rezultate obdelali še numerično. V obeh slojih smo opazili večje razlike v tokovih le ob obalah, ob odprtem robu in bližje dnu, kjer je vpliv robnih pogojev večji, drugod so razlike minimalne. Za nadaljnje delo lahko uporabimo katerokoli izmed obravnavanih povprečenj dejanskega vetra, saj napake prostorskega povprečenja vetra ne presegajo nezanesljivosti simulacij modela PCFLOW3D in vhodnih podatkov. The thesis addresses the impact of spatial averaging of actual winds on the circulation in the Gulf of Trieste. The given wind fields were averaged from resolution of 150 x 150 m over four- and ninefold larger areas, the latter in two ways, in each hour of the seventy-two hour simulation period. Hydrodynamic simulations were performed with the PCFLOW3D model. The results were mapped at the depths of 0.5 m and 10.5 m. Due to small differences between the currents we also analysed the results numerically. In both layers we observed significant differences in currents only near the coastline, at the open boundary and closer to the seabed, where the boundary conditions have greater impact, while elsewhere the differences were minimal. Any of the examined wind averaging techniques may be used for further modelling, as the error of the space averaging does not exceed the inaccuracy of the PCFLOW3D model and of the input data. gradbeništvo diplomska naloga UNI B-VOI matematično modeliranje model PCFLOW3D Tržaški zaliv krajevno povprečenje vetra mathematical model PCFLOW3D Gulf of Trieste spatial averaging of wind true false false A.
