Cross-flow-induced chaotic vibrations of heat-exchanger tubes impacting on loose supports
M.P. Païdoussis,G.X. Li +1 more
TL;DR: In this paper, the chaotic dynamics of heat exchanger tubes impacting on the generally loose baffle plates is studied using an analytic model that involves delay differential equations, and the critical flow velocity for the local instability of the flexible cylinder near the static equilibrium position is obtained by assuming a harmonic solution in the discretized linearized model and solving the resulting algebraic equations.

TL;DR: In this paper, a simple theoretical model was developed from first principles for the fluidelastic instability in heat exchanger tube bundles, and a series of experiments were conducted to verify the basic assumption that only a single tube need be modeled in a flow channel which preserves the basic geometry of the array.
