Abstract

 Green energy applications have been a promising research area last two decades.
One of these applications is using the power of wind for electrical power
generation; wind turbines with different designs have great importance in this
field. However, capturing energy from wind by using traditional wind farms has
several limitations such as large installation space, specified airflow conditions,
shading effect, noise, and design and maintenance complexity. Bladeless wind
turbines have been used to convert wind energy into useful kinetic energy to
overcome these obstacles. This paper introduces numerical and experimental
investigations of a bladeless wind turbine for harvesting energy from wind. The
proposed design has a cylindrical structure to resonate at a wide range of wind
speeds and directions, which can maximize the harvested energy. Eigenfrequency simulation modules were developed to determine the structure’s natural
frequencies and mode shapes which aimed for continuous tunning with the
generated vortex shed frequency. Furthermore, the numerical investigations
extended to simulate the fluid-structure interaction (FSI) analysis to accurately
define the dynamic response of the bladeless wind turbine under different air-flow
conditions. The resulting kinetic energy is delivered to an alternator to convert it
into electrical power.
