L`étude de la main et de l`avant-bras d`un nageur de compétition utilisant le modèle de la dynamique des fluides

(The study of swimmer's hand and forearm using computational fluid dynamics)

The aim of the present study was to apply the computational fluid dynamics methodology to study the hand/forearm forces in swimming 3-D configuration. Methods Models used in the presented simulations were created in CAD, based on real dimensions of a right adult human hand/forearm. The governing system equations considered was the incompressible Reynolds averaged Navier-Stokes equations implemented in the Fluent® commercial code. The numerical simulation was carried out in three dimensions of the whole domain in steady flow. The dynamic fluid forces produced by the hand/forearm, lift and drag, were measured in this study. Results The drag coefficient was the main parameter for propulsion, with the maximum value of the propulsion force corresponding to a pitch angle of 90°. The lift coefficient seemed to be a parameter with less influence to generate the propulsive force with pitch angles of 0° and 90° but it is important with a pitch angle of 45°.
