Cylinder Drag Reduction Using Discrete Surface Roughness: An Experimental Investigation Into the Effect of Cylindrical Roughness Elements

This thesis investigates the influence of Cylindrical Distributed Roughness Elements (polka-dots) on cylinder flow, with a focus on potential applications in sports aerodynamics. The primary goals are twofold: to explore the mechanism behind tripping and to analyse how the dimensions (height, width, spacing) of polka-dots affect flow...
