Construction and calculation of a darrieus vertical axis wind turbine with H-Rotor

Since ancient times humans have attempted to harness the wind energy through diversified means, vertical axis wind turbines (VAWTs) have been one of the most important pieces of equipment to achieve this. The purpose of this work is to calculate and construct a small-size Darrieus H-Rotor, so to be able to construct the turbine one day. An H-Rotor has a simple construction, however the calculation is complicated because the aerodynamic analysis is quite complex. Furthermore there are some opportunities to test the performance of the rotor this is also included in this thesis. The difficulty is that there has not been many investigations nor much research in this area of wind energy. Because of this, it is not easy to gather important information because the technology of Darrieus type turbines is relatively new --Abstract
