Numerical modeling of vertical axis wind turbine with air guides

Currently, obtaining energy from renewable sources, as never before, it has become one of the most important areas, but at the same time challenges in human activities. This is the effect of many factors simultaneously, including because of the media trumpeted the greenhouse effect, the necessity of reducing CO2 emissions, shrinking natural resources, and thus the desire to protect their welfare including conservation (including natural resources) for future generations. The paper presents the results of preliminary numerical analyzes of work for vertical axis wind turbines equipped with air guides. The carried out analyzes indicate the potential possibility of using this type of construction in practice. The obtained power factor value is higher than in classic wind turbines with a vertical axis. The conducted analyzes also indicate the possibility of optimizing the proposed constructional solution in order to increase efficiency of obtaining energy from the wind.
