Visualization of flow structures from a vertically long human nail.

Bio Fluid Dynamics plays a major role in sports aerodynamics especially swimming, cycling, etc., the need for aerodynamic analysis is due to drag production and its impact on the timing consumed by the person during the race. This project considers a special nail for studying the flow structures formed by it when subjected to turbulent flow. The generation of vortices is visualized using a laser sheet. The results suggest that the vortices have an influence on the wake structure and it is also affected by the orientation of the nail. [ABSTRACT FROM AUTHOR]
