초록

A fairing for the reduction of vortex-induced vibration and the minimization of drag about a substantially cylindrical element immersed in a fluid medium. The fairing also eliminates the galloping phenomenon typically associated with a teardrop-shaped fairing. The fairing having a U-shaped cylindrical shell with opposing edges defining a longitudinal gap and parallel fins extending outwardly from the opposing edges of the shell, the parallel fins being positioned so as to reduce vortex-induced vibration, minimize drag and to eliminate the galloping pheno...

청구항

What is claimed is: 1. A fairing for the reduction of vortex-induced vibration, the minimization of drag and the elimination of the galloping phenomenon about a substantially cylindrical element immersed in a fluid medium, comprising: a one-piece fairing having a U-shaped cylindrical shell portion at a leading edge of the faring with opposing edges extending toward a trailing edge of the fairing, the opposing edges defining a longitudinal gap, wherein the gap provides an opening that allows for placement of the substantially cylindrical element through ...
