Characteristics of Flow Through a Bladeless Wind Turbine with Delta Vortex Generators
摘要
In this work, the design and analysis of a bladeless wind turbine with built-in vortex generators are presented. The work’s goal was to examine the turbine’s performance at various wind speeds by utilizing ANSYS for the fluid-structure interaction (FSI) study and autodesk fusion for the design. Five and fifty meters per second of wind were applied to the wind turbine model, illustrating a range of wind speeds pertinent to many applications. Innovative ideas were used in the design of the bladeless wind turbine to maximize wind energy efficiency. A crucial part that was incorporated into the turbine to enhance its performance through vortex shedding is the vortex generator. Through the vibrations brought on by vortex shedding, this design strategy enhanced power generation. The results verify that the best design to be used at different speeds and heights to provide the required turbulence and velocity will be the random vortex generation as the results for the turbulence for 1 m cylinder with 5 m/s wind speed, 3 m cylinder with 5 m/s wind speed, 1 m cylinder with 50 m/s wind speed, and 3 m cylinder with 50 m/s wind speed are 0.6252 m2/s2, 0.5303 m2/s2, 39.32 m2/s2, and 56.77 m2/s2, respectively. As for the velocity, the results are 1.92 m/s, 4.596 m/s, 39.51 m/s, and 22.97 m/s, respectively. Moreover, the design that provides a structured and organized pressure would be the distributed vortex generation at different speeds and heights as the results are −14.36 Pa, −14.28 Pa, −755.1 Pa, and −1190 Pa, respectively.
