Abstract

The main objective of this study is to clarify experimentally the vibration characteristics of tube bundle subject to an upward cross flow. In-line array of tubes widely used in shell-and-tube type of heat exchangers was simulated by transparent glass rods mounted flexibly over the whole tube bundle. Displacement of the vibrating rods was captured by high speed video camera whereas instantaneous velocity fields around the rods were obtained by Particle Image Velocimetry (PIV). The results confirmed that the vibration characteristics of tube bundle are closely related to the velocity fluctuation of the surrounding flow field.
