6880476 Recesses on a surface  
Formations on the surface of bodies for reducing the drag relative to a medium which the body is located in or close to. The formations comprise a plurality of cavities ( 1,20,40,60 ). The surface...
6345791 Streamwise variable height riblets for reducing skin friction drag of surfaces  
A series of parallel riblets extend from a smooth, aerodynamic surface for reducing the skin friction drag of the surface an airstream flows around it. The riblets extend longitudinally along the...
6092766 Process for forming a surface for contact with a flowing fluid and body with such surface regions  
A surface for contact with a fluid, flowing in a flow direction (A) over the surface, is provided with grooves (1) to prevent flow separations at low, local Reynolds numbers. The grooves extend...
5445095 Polymer/riblet combination for hydrodynamic skin friction reduction  
A process for reducing skin friction and inhibiting the effects of liquid turbulence in a system involving the flow of a liquid along the surface of a body, e.g. a marine vehicle, includes...
5340054 Suppressor of oscillations in airframe cavities  
The oscillations found to occur in the cavities of an structural frame moving through a fluid are substantially eliminated by the adoption of perturbation elements located at the leading edge of...
5133516 Drag reduction article  
A conformable drag reduction article is provided having a patterned surface capable of reducing drag resistance by fluid flowing thereover.
5114099 Surface for low drag in turbulent flow  
A nonsmooth surface of an object in a fluid flowstream permits a reduction of turbulent drag. The surface shape is designed to approximate a minimal surface and satisfies the equation...
5069403 Drag reduction article  
A conformable drag reduction article is provided having a patterned surface capable of reducing drag resistance by fluid flowing thereover.
4989810 Method and apparatus for influencing a laminar turbulent boundary layer transition on bodies in flow  
A method and an apparatus for influencing a laminar-turbulent boundary layer transition on bodies in flow is indicated. The disturbances are in this case introduced into the boundary layer in an...
