Deep Dynamic Stall

Investigating Pressure and PIV for Understanding Deep Dynamic Stall Phenomena

Wind turbines play a crucial role in the worldwide effort to embrace sustainable energy, utilizing sophisticated aerodynamic principles to efficiently capture wind energy. A thorough comprehension of deep dynamic stall, a phenomenon that greatly impacts wind turbine performance, ...
The thesis presents an analysis of unsteady vortex shedding and vortex induced vibrations (VIV) on wind turbine blades using a combination of Stereoscopic Particle Image Velocimetry (SPIV) and Computational Fluid Dynamics (CFD). A spanwise uniform blade with a symmetric NACA0021 ...
