Numerical Simulation Study on the Influence of Yaw-to-Wind Angular Velocity on Wind Turbine Aerodynamic Characteristics

Effects of Yaw Error on Wind Turbine Running Characteristics Based on the Equivalent Wind Speed Model

Natural wind is stochastic, being characterized by its speed and direction which change randomly and frequently. Because of the certain lag in control systems and the yaw body itself, wind turbines cannot be accurately aligned toward the wind direction when the wind speed and wind direction change frequently. Thus, wind turbines often suffer from a series of engineering issues during operation,...

A Multi-prong Study on Aerodynamic Characteristics of Archimedes Spiral-type Wind Turbine Blade

This research describes aerodynamic characteristics of small-scale wind turbine blade, called Archimedes spiral wind turbine blade. Numerical approaches on the prediction of aerodynamic performance of the blade have been conducted. Both steady and unsteady state numerical simulations using ANSYS CFX are performed on the several cases of rotating speeds. Large scale tip vortex is captured and gr...

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 ...
