Abstract
The objective of this study is to show the effect of guide vane solidity on the performance of straight-bladed vertical axis wind turbine with a directed guide vane row. The experimental study was carried out by a wind tunnel. The wind tunnel with a diameter of 1.8 m is open jet type. The rotor has 3 straight blades with a profile of NACA4518, a chord length of 100mm, a diameter of 600mm and a blade height of 700mm. The guide vane consists of some arc plates. The wind velocity is constant at 8m/s. As a result, it has been concluded that the turbine performance depends on the guide vane solidity.
