RB1-10 FIVER - A New Design Concept to Prevent Tube Damage from Flow-Induced Vibration in Shell-and-Tube Heat Exchangers

J. M. Chenoweth

A new design concept called FIVER, an acronym for Fluidelastic Instability Vibration Evasion Restraints, has been conceived at HTRI that will extend the operating range for shell-and-tube heat exchangers. Flow-induced tube vibration damage can be avoided with a slight increase in the shellside pressure drop. The principle has been successfully demonstrated in isothermal experiments in the Argonne test exchanger using a bundle with a square tubefield layout.
