1. 1. Two-dimensional Study of Blade Profiles for a Savonius Wind Turbine

   University essay from Uppsala universitet/Elektricitetslära

   Author : Johanna Sundberg; Martina Lundberg; Julia Solhed; Aikaterini Manousidou; [2020]
   Keywords : Savonius rotor; vertical axis wind turbines; Ansys Fluent; k-omega SST; overlap ratio; blade arc angle;

   Abstract : A Savonius wind turbine is a self-starting vertical axis rotor. It can be designed to be compact in size and also produces less noise which makes it suitable to integrate into urban spaces such as rooftops and sign-poles. READ MORE

3. 2. A stochastic analysis of Turbulence Intensity influence over various sizes of HAWT : Study of hypothetical relationship between Rotor Diameter and influence level of Turbulence Intensity

   University essay from Högskolan i Halmstad/Energivetenskap

   Author : Allen Christo Nicholas; [2016]
   Keywords : Turbulence intensity; power performance; power deviation; power coefficient; tip speed ratio.; Turbulensintensitet; effektuttag; effektavvikelse; verkningsgrad; löptal;

   Abstract : This disquisition aims for the study of turbulence intensity influence over the power performance of different sizes of turbines with the intent to validate a hypothesis. The hypothesis formulated for the analysis is the relationship between the rotor diameter (turbine size) and turbulence intensity. READ MORE
