02148 For reduce the turbulence of a fluid and method of transporting

摘要

A turbulence attenuator consists of a surface structure inside the pipe. The structure has a geometry which damps turbulence at different amplitudes in a limited layer of the fluid laying adjacent to the surface. The surface structure has a first set of components (O1) of one amplitude (a1) and a second set of components (O2) of a second amplitude (a2) which is superimposed on the first. The two sets of components are designed to damp turbulence in the flow at different amplitudes. The transporting pipeline can be of steel with the attenuator surfaces produced by mechanical or chemical mechanisms, or of a composition material.
