Abstract:Unsteady aerodynamic forces play a crucial role in phenomena such as vortex-induced vibration and galloping. However, the influence of turbulence on unsteady aerodynamics remains far from been fully understood. In this study, a series of forced vibration model and rigid model wind tunnel tests were conducted in both a uniform flow and three different turbulent boundary layer flows with varying turbulence conditions to investigate the unsteady aerodynamic forces of a slender three-dimensional prism.
