Abstract

U ovom radu prikazani su rezultati studije koje su provedene s ciljem određivanja klime valova oko niza hipotetskih valnih uređaja. Kao cilj ovog rada razmatraju se promjene visine vala uzvodno i nizovodno od postavljenih uređaja za različite razine apsorp cije vala. To se postiže modeliranjem valnih uređaja kao poroznih struktura s različitim razinama poroznosti, uz uvođenje u obzir djelomične refleksije i djelomičnog prijenosa. U tu svrhu koristi se valni model MIKE 21 Boussinesq. Rezultati su prikazani u obliku značajnih polja visine valova. Rezultati provedenih numeričkih simulacija prikazani su u vidu prostorne raspodjele značajnih valnih visina (polja H S ) na prostornoj domeni Bousinesq numeričkog modela Ova studija ilustrira kako varijacije u apsorpci ji valova od strane uređaja utječu na stupanj refleksije valova i prijenosa oko uređaja. Rezultati provednog istraživanja pokazali su da se primjenom 2 reda konvertera postavljenik u 5 naizmjeničnih kolona prosječna incidenta značajna valna visina smanjuje za prosječno 47.3% , a ukoliko se postavi 5 redova konvertera smanjenje je prosječno 77,2%.

Abstract (english)

This paper presents the results of a study carried out to determine the change in wave climate around an array of hypothetical wave devices. The main objective of this work is to investigate the change in wave height in the upstream and downstream of the devices for different levels of wave absorption. This is achieved by modeling the wave devices as porous structures with different porosity levels, with the inclusion of partial reflection and partial transmission. The MIKE 21 Boussinesq wave model is used for this purpose.
The results are presented in the form of significant wave height fields. This study illustrates how the variations in wave absorption by the devices affect the degree of wave reflection and transmission around the devices. The results of the conducted research showed that by applying 2 rows of converters placed in 5 alternating columns, the average incident significant wave height is reduced by an average of 47,3%, and if 5 rows of converters are installed, the reduction is an average of 77,2%.
