<p>A drag reduction arrangement for the body (12, 13, 14) of an athlete moving through a fluid medium (2), comprises a device (11) attachable to the athlete's body for delaying the onset of boundary layer separation at a trailing surface thereof. The device preferably comprises an array of vortex generators (11). As a result, form drag is reduced by an amount which is substantially greater than any increase in skin friction due to the presence of the vortices.</p> |
