Fluid-Structure Interaction Analysis on Horizontal Wind Turbine Blade
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 1
Abstract
The research and advancements in green-energy industries like wind energy system technology has gained an increased interest in twenty-first century due to the reduction of natural resources and thus requires the standardization of the main components of wind turbines to reduce cost. In this study, a coupled analysis of both CFD and static structural for a horizontal axis wind turbine blade is carried out. The blade is allowed to pass through a fluid flow of 12m/s in a computational chamber using Fluent. The pressure thus produced on the blade surface is determined. Further analysis is done by dragging the pressure distribution as an input for structural platform along with a varying rotor speed of 5, 10, 15 and 20 revolutions per minute for finding the Stress and deformation in the blade. The work is carried out for both two and three bladed turbine with change in Tip Speed Ratio and a relative comparison is drawn. Besides, the natural frequencies of the blade are computationally derived and are being validated by refining the mesh
