An alternative technique for investigating fluid flow around the hand during front crawl
conference contribution
posted on 2014-02-03, 10:12 authored by Anjali Udeshi, Ben Halkon, Jeremy CouplandJeremy CouplandThis paper presents the novel application of a technique for measuring flow around the hand during a simulated swim stroke
with a view to enable a better understanding of propulsion generation in swimming. The technique relies on the
instantaneous, non-intrusive, volumetric measurement of 3D velocity fields using a commercially available optical
measurement system. A hand and forearm model was towed through a water tank to replicate the pull phase with fluid flow
data being captured at regular intervals in a fixed volume through which the model moved. The measurement system
included a single body, three-sensor probe for capturing pairs of images which were then processed to determine particle
velocities and to characterise the flow. The results were used to investigate changes in mean velocity for six experimental
cases based on three different angles of attack and two towing speeds. The results showed that the V3V system could be
used to capture velocity data around the hand and for a 45° increase in angle of attack, the velocity magnitude of the flow
reduced by half, indicating the presence of lift forces.
