Summary

An experimental study of fluid-elastic instability in multispan heat exchanger tube arrays is presented. The experiments were conducted in a wind tunnel using a parallel triangular array of brass tubes. A variety of configurations was studied with up to four support plates, such that the spans between supports were of different lengths. An alternative simi-empirical model is presented which predicted the observed critical model of instability and gave a conservative estimate of the critical velocity for all seven of the different configurations studied.
