Abstract
The results are presented of an experimental investigation into the possible modes of gas-excited vibration of a single row of tubes in a heat exchanger at typical practical spacings. The vibrations discussed are vortex excited and, for damping which permits large amplitudes, occur at values of the Strouhal number 0·26 < ND/V < 0·89. The critical range of ND/V is affected by both Reynolds number and spacing. Four distinct modes of vibration are found, all consisting of motion principally transverse to the flow direction.Keywords
