Downhill skateboard aerodynamics

Computational Fluid Dynamics has been used to perform a detailed aerodynamic analysis of a downhill skateboarder. The modelled geometry is that of a British downhill skateboarder, acquired using non contact laser scanning. Three helmets used by the skater were also compared, which revealed how each helmet directed the flow of air around and onto the body of the skateboarder. A study was also conducted into the influence of drafting, a tactical manoeuvre used in the race by skateboarders. This revealed how drafting skaters should position themselves behind a lead skater to minimize the drag force acting upon them.
