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.
