Abstract

Experiments were done to analyze drag measurements of a swimmer in the streamline position. Drag readings were recorded at different velocities while the swimmer had two different head positions: ears between arms, and ears below arms. Several anthropometric measurements were taken to ensure accurate correlation analysis. Along with the drag investigation, fluid particle velocity measurement analysis was conducted. The Digital Particle Image Velocimetry (DPIV) technique was used to process digital video taken of a swimmer while he or she was tethered in front of an underwater window doing the freestyle stroke. Passive drag results indicated the drag did not significantly correlate with the head position. The velocity profile of the flow created by swimming was accurately created, suggesting further investigations of the underwater dolphin kick.
