Abstract:
A reduced-vibration tube array comprising:a plurality of tubes in a fixe arrangement, each tube having an inner surface; a plurality of tunable damping members each positioned within a corresponding one of said tubes; each damping member resembling an elongated strip having a first contoured interface region characterized by predetermined quantity of bracing points for selectively contacting said inner surface of said corresponding tube, said first interface region being sized and shaped in accordance with said tube such that said bracing points of said first interface region are spaced apart a predetermined, first vibration-reducing distance from said tube inner surface at equilibrium; whereby mechanical interaction between said bracing points located on said elongated strip and said tube inner surface is effective to reduce vibration by a damage-reducing degree and whereby said damping members are adapted to impart desired fluid flow and mechanical interaction properties selected in accordance with predetermined tube parameters.
