Abstract

V današnjem času je skrb za čisto okolje bistvenega pomena večine držav razvitega sveta. Zelo pomembno vlogo pri tem imajo tudi obnovljivi viri energije, kamor sodijo lesna biomasa, vodna energija, sonce in veter. Sam sem se osredotočil na vetrno energijo-kinetično energijo vetra, ki jo s vetrnimi turbinami pretvarjamo v mehansko energijo in nadalje s vetrnimi elektrarnami v električno energijo. S programskim paketom Ansys CFX 14.5 sem napravil simulacijo poenostavljene vetrne turbine s horizontalno osjo pri različnih hitrostih vetra. Simulacijo sem napravil pri dveh različnih vrtilnih frekvencah, zanimal me je navor, moč in izkoristek cp. Na osnovi dobljenih rezultatov lahko sklepamo, da prihaja pri različnih hitrostih vetra in pri različnih vrtilnih frekvencah do različnih rezultatov in da moč s hitrostjo narašča.

Secondary abstract:	In present time clean enviroment is the number one issue for the most of developed countries in the world. Renewable energy sources which are wood, water energy, sun and wind energy play very impotant role in the process of environmentol care. My work is focused on windenergy-kinetic energy of the wind. We use wind turbines to transform wind energy into mechanic energy and later with wind plant into electric energy. With program Ansys CFX 14.5 I made a simulation of a simple wind turbine with horizontal axes at different wind speed. I made a simulation of two various frequencys, I was interested in torque, power and efficient. Based on the resultats we come to a conclusion, that at various wind speed and frequencys the results are different and that the power with speed increases.
