Abstract
Ovaj završni rad istražuje fenomene refrakcije i uplićavanja valnog polja kroz dva pristupa: fizikalni i numerički model programiran u MATLAB-u. Fizikalni model koristi pravokutnu plastičnu kutiju dimenzija 34 x 54 cm, LED rasvjetu, spužvu za sprječavanje refleksije valova, mini modele obale napunjene cementnom pastom, električni motor s lopaticom za generiranje valova i digitalni mjerač razine vode. Eksperimenti su provedeni postavljanjem različitih prepreka i modela obale kako bi se proučili fenomeni refrakcije i uplićavanja, pri čemu su se indirektno mjerile visine valova. Numerički model za izračunavanje refrakcije i uplićavanja implementiran je u MATLAB-u, koristeći diskretizaciju prostorne domene pomoću trokutastih konačnih elemenata. Cilj rada je usporediti rezultate dobivene iz fizikalnih eksperimenata s onima iz numeričkih simulacija te analizirati točnost i učinkovitost oba pristupa. Naši rezultati su pokazali visoku razinu podudarnosti između fizikalnog i numeričkog modela, uzimajući u obzir moguća odstupanja zbog eksperimentalnih ograničenja i numeričkih aproksimacija. Zaključno, rad istražuje i ukazuje na prednosti i izazove oba pristupa u analizi ponašanja valnog polja uslijed procesa refrakcije i uplićavanja.
Abstract (english)
This thesis investigates the phenomena of refraction and shoaling in wave fields through two approaches: a physical model and a numerical model programmed in MATLAB. The physical model utilizes a rectangular plastic box measuring 34 x 54 cm, LED lighting, a sponge to prevent wave reflection, mini coastal models filled with cement paste, an electric motor with a paddle for generating waves, and a digital water level meter. Experiments were conducted by placing various obstacles and coastal models to study the phenomena of refraction and shoaling, indirectly measuring wave heights. The numerical model for calculating refraction and shoaling was implemented in MATLAB, using spatial domain discretization with triangular finite elements. The aim of this paper is to compare the results obtained from physical experiments with those from numerical simulations and to analyze the accuracy and efficiency of both approaches. Our results showed a high level of correspondence between the physical and numerical models, taking into account possible deviations due to experimental limitations and numerical approximations. In conclusion, the paper explores and highlights the advantages and challenges of both approaches in analyzing wave field behavior due to the processes of refraction and shoaling.
