Definitions

  • Fig. 13 is a diagrammatic front elevation of a human leg having a garment with double trip mechanisms, a front panel with riblets and mesh around the remainder of the leg.
  • any turbulent flow inside the boundary layer along the fabric can be channeled.
  • riblets 42 i.e., small parallel ridges in the fabric with the riblets extending preferably parallel to the predominant air flow.
  • any turbulent flow inside the boundary layer along the fabric can be channeled.
  • riblets channel the turbulent flow and reduce the amount of interference between adjacent vortices and, therefore, reduce energy los ⁇ e ⁇ to di ⁇ organized turbulence and maintain the boundary layer momentum. This allows the flow to remain attached to the body longer which reduces the size of the wake and thus the pre ⁇ ure drag.

Abstract

L'invention concerne un procédé et un système pour réduire la force de traînée sur le mouvement du corps humain dans l'air ou dans d'autres milieux fluides, et pour améliorer le transfert thermique. Ce procédé consiste à placer des mécanismes de déclenchement (22) en des emplacements prédisposés sur le corps humain. Ces mécanismes de déclenchement (22) constituent des protubérances allongées adaptées pour intercepter l'écoulement laminaire du fluide à travers le corps, et les transformer prématurément l'écoulement laminaire en turbulences. Cela permet d'augmenter la pression aval sur le corps, tout en assurant un déplacement plus libre du corps dans le milieu fluide.
