Résumé :

It is now well known that swimming drafting leads to a reduction in energy spent to overcome drag forces (friction, wave and pressure) and enhances gains time in competitive swimming (Brisswalter and Hausswirth, 2008 ; Bixler et al. 2007 ; Vennell et al 2006 ; and Chatard et al. 1998). In underwater swimming, the flow past a swimmer induces a trailing adverse pressure gradient area in its near wake. Swimming drafting behind and close to another swimmer consequently leads to a reduction in pressure drag induced by the lead swimmer.
At the authors knowledge, the only study in literature dealing with numerical analysis of drafting in swimming is the one of Silva et al. (2008) using CFD in 2D configuration and where the distance between swimmers varied in the range 0.5<d<8.0 m. The present study differs from this work as far as it focuses on a shorter distance between swimmers (0<d<0.5 m) in touch with the experimental conclusions by Chatard and Wilson (2003).
