Abstract

Et system er beskrevet som omfatter et vesentlig sylindrisk element (204), minst ett plategangselement (206a) rundt en periferi av det sylindriske element der minst ett av plategangselementene er lukket og omfatter en tykkelse (T) målt i en retning langs en langsgående akse av det sylindriske element som er mindre enn to ganger en ytterdiameter (D) av det sylindriske element og der plategangselementene virker for å redusere vibrasjonen av det sylindriske element når det sylindriske element utsettes for en fluidstrøm.
