Abstract
The invention is a structure for inhibiting the turbulence phenomena of a fluid, exhibiting a surface geometry comprising at least one series of inhibition surfaces which inhibit turbulence present in a boundary layer of the fluid in proximity to the wall of the structure and which extend substantially longitudinally in the direction of flow of the fluid. The inhibition surfaces comprise at least a first series of surfaces (,) of amplitude a,and at least a second series of surfaces (,) of amplitude a,. The second series of surfaces (,) is arranged so as to be superposed on the first series of surfaces (,), the first series of surfaces (,) allowing inhibition of at least turbulence of great amplitude and the second series of surfaces (,) allowing inhibition of at least turbulences of low amplitude. The structure has an application for forming at least part of a pipe for conveying a pressurized gas.
