Abstract
Završni rad istražuje refleksiju i difrakciju valova kroz dva pristupa: fizikalni model i numerički model u MATLAB-u. Fizikalni model koristi plastičnu kutiju (34 x 54 cm), LED-ice, spužvu za smanjenje refleksije valova od stijenki kutije, 3D isprintane modele obale, električni motor za stvaranje valova i digitalni mjerač razine vode. Eksperimenti su provedeni s različitim preprekama i modelima obale, pri čemu se indirektno mjerila visina i period valova. Numerički model u MATLAB-u izračunava plan refrakcije, uplićavanje i refleksiju uz zadavanje koeficijenta refleksije u obalnoj zoni. Na temelju rezultata numeričkog modela, difrakcija je naknadno proračunata grafo-analitičkom metodom. Cilj rada je usporediti rezultate fizikalnih eksperimenata i numeričkih simulacija te analizirati njihovu točnost i efikasnost. Rezultati pokazuju visoku podudarnost, uz razmatranje odstupanja zbog eksperimentalnih ograničenja i numeričkih aproksimacija. Zaključno, ovaj rad ukazuje na prednosti i izazove oba pristupa te pruža potencijalne smjernice za buduća istraživanja.
Abstract (english)
This thesis investigates the reflection and diffraction of waves through two approaches: a physical model and a numerical model using MATLAB. The physical model uses a plastic box (34 x 54 cm), LEDs, a sponge for reucing the reflection, 3D printed coastal models, an electric motor for wave generation, and a digital water level sensor. Experiments were conducted with various obstacles and coastal models, indirectly measuring the height and the period of the waves. The numerical model in MATLAB calculates refraction patterns, shoaling, and reflection by assigning a reflection coefficient in the coastal zone. Based on the results of the numerical model, diffraction was subsequently calculated using a graph-analytical method. The aim of the thesis is to compare the results of physical experiments and numerical simulations and to analyze their accuracy and efficiency. The results show high correspondence, considering deviations due to experimental limitations and numerical approximations. In conclusion, this thesis highlights the advantages and challenges of both approaches and provides potential guidelines for future research.
