Tube arrays in industrial components such as heat exchangers and steam generators are susceptible to damage due to fluidelastic instability (FEI). This study focuses on the modelling of fluidelastic instability in tube arrays subjected to cross-flow. There is agreement on the idea of introducing a time delay in FEI models. Although it is one of the key parameters for FEI models, the phenomenon behind this time delay is still subject to many possible explanations, and the underlying physics is still not well understood.In the present work a new time delay formulation for the class of the quasi-steady FEI models is derived in the frequency domain in the form of an Equivalent Theodorsen Function.Unsteady and quasi-static fluid forces were measured to develop the time delay formulation.The effect of Reynolds number on the static force coefficients was also investigated. The time delay function was found to be also dependent on the Reynolds number which implies that the fluidelastic instability is also Reynolds number dependent. Comparison to other time delay functions proposed in the quasi-steady and quasi-unsteady models is made. An initial overshoot in the lift force was observed for the present model.

“…This flow periodicity may be generated by acoustic resonance or by another mechanism referred to as Strouhal periodicity. Both mechanisms will produce similar tube responses, a fact that led Weaver & Fitzpatrick (1988) to dismiss as unreliable much earlier (pre1980) Strouhal data for tube arrays, since it was obtained from heat exchangers prone to acoustic resonance.…”

Fast numerical simulation of vortex shedding in tube arrays using a discrete vortex method

Vortex shedding may occur in tube arrays, resulting in strong excitation forces at discrete frequencies. In the past the Strouhal numbers governing vortex shedding in these systems were determined primarily by experiment. This paper presents a computationally inexpensive method of numerical simulation for the unsteady flow through a rigid normal triangular tube array which determines both the frequency of vortex shedding and the instantaneous flow structure. The technique used is based on a discrete vortex method similar to the cloud-in-cell approach which has been applied to flow problems for small numbers of cylinders. However, in the current implementation the flow velocity calculation is carried out on an unstructured grid using a finite element discretization. Thus, the complex geometry associated with a tube array can be easily accommodated. The method, referred to as the "Cloud-in-element" method, is validated for the standard case of flow over a single cylinder and then applied to flow through a normal triangular array with a pitch-to-diameter of 1.6. The Reynolds number is 2200. The Stouhal number obtained from the numerical simulation is 1.27, which is within 6% of the value available in the literature. Qualitatively, the vortex shedding pattern obtained is in agreement with published flow visualization.
