Abstract
U okviru ovog diplomskog rada su provedene 4 faze procesa razvoja mikro vjetroturbine nazivne snage 200 W: preliminarno projektiranje, izrada 3D CAD modela rotora vjetroturbine, CFD simulacije optjecanja zrakom rotora vjetroturbine, te 3D ispis prototipa rotora vjetroturbine primjenom rapid prototyping tehnologije. Peta faza razvojnog procesa, FEM analiza naprezanja, deformacija i životnog vijeka strukture rotora vjetroturbine, nije predmet ovog diplomskog rada. Preliminarnim proračunom su dobivene vrijednosti osnovnih geometrijskih karakteristika vjetroturbine na osnovi kojih je izgrađen 3D CAD model rotora vjetroturbine. Za potrebe CFD simulacije optjecanja rotora, oko 3D modela rotora izgrađena računska domena, a potom je unutar računske domene generirana mreža konačnih volumena. Nakon toga su relativno brzo, uz vrlo dobru konvergenciju (postizanjem, po svim kriterijima konvergencija, reziduala od 10-3 i 10-6), provedena CFD simulacija, koja je kao rezultat pokazala polja tlaka i brzine unutar zadane računske domene i po površini same lopatice rotora, te numerički iznos snage ove vjetroturbine. Na kraju se primjenom rapid prototyping tehnologije, pomoću 3D pisača, ispisao 3D prototip vjetroturbine.
Abstract (english)
Within this master thesis, 4 phases of the development process of a micro wind turbine with a nominal power of 200 W were carried out: preliminary design, development of a 3D CAD model of a wind turbine rotor, CFD simulation of air circulation of a wind turbine rotor, and 3D printing of a prototype of the wind turbine rotor using the rapid prototyping technology. The fifth phase of the development process, FEM analysis of stresses, deformations and service life of the wind turbine rotor structure, is not the subject of this thesis. Preliminary calculations obtained the values of the basic geometric characteristics of the wind turbine on the basis of which the 3D CAD model of the wind turbine rotor was built. For the purposes of a CFD simulation of airflow around the rotor, a computational domain was built around the 3D model of the rotor, and then a network of finite volumes was generated within the computational domain. After that, the CFD simulations were performed relatively quickly, with very good convergence (achieving, by all convergence criteria, residuals of 10-3 and 10-6), which resulted in the pressure and velocity fields within the given computational domain and on the surface of the rotor blade itself, as well as the numerical amount of power of this wind turbine. Finally, with the use of a 3D printer and rapid prototyping technology, a 3D prototype of the wind turbine was printed.
