Wind power plants are increasingly being installed across the world to combat energy deficits and climate change. One of the policy constraints for installing wind turbine plants is acoustic emissions from blades during operation. In this work, a con

Broadband noise generation from wind turbine blades is one of the fundamental aspects of flow-induced noise. Besides the turbulent boundary layer flow over the blades, factors such as the angle of attack, the turbulence intensity, the trailing edge t

Wind power plants produce energy by utilising the kinetic energy available from wind. Turbine blades undergo millions of revolution during lifetime and subjected to wear and tear due to unsteady aerodynamic forces. In this work, steady-state blade el
