Performance Characteristics of A Micro Wind Turbine Integrated on A Noise Barrier

An Investigation on Performance of Shrouding a Small Wind Turbine with a Simple Ring in a Wind Tunnel

Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated in a wind tunnel. The duct is shaped using rolling steel sheets on a sloping surface and finally...

Wind Turbine Noise Issues

Wind turbine noise.

The evidence for adequate sleep as a prerequisite for human health, particularly child health, is overwhelming. Governments have recently paidmuch attention to the effects of environmental noise on sleep duration and quality, and to how to reduce such noise. However, governments have also imposed noise from industrial wind turbines on large swathes of peaceful countryside. The impact of road, r...

Effect of Reduced Frequency on the Unsteady Aerodynamic Performance of a Wind Turbine Blade Section

The blades of wind turbines are the most important parts in producing power output. In this study, a section of a 660 KW wind turbine blade will be installed in Iran in near future was tested in a wind tunnel. In addition to steady tests, various unsteady tests including the effects of reduced frequency, mean angle of attack, and amplitudes were carried out. The preliminary results show strong ...
