A NOVEL DESIGN FOR VERTICAL AXIS WIND TURBINE
Resumo
In this study a new design for a Vertical Axis Wind Turbine is presented. First, four different blade designs
were developed and compared initially using Computational Fluid Dynamics (CFD). A two-dimensional transient model was created in Fluent using dynamic mesh in order to evaluate the performance of the turbine at different wind speeds. The performance criterion is based on higher blade speed and lower drag coefficient. Accordingly, a blade design was chosen and a prototype was built. This prototype was tested in a wind tunnel to evaluate the power generated by the turbine at different wind speeds. The turbine was
connected to a generator in order to obtain a relationship between wind speed and power. The turbine produces high torque and runs very quiet. There is no flickering effect and is safe for birds. The outcomes of this study prove that the new blade design is an effective alternative for the Vertical Axis Wind Turbine.
