Nonlinear dynamics of tube arrays in cross flow

PDF Version Also Available for Download.

Description

Fluidelastic instability of loosely supported tube arrays was studied analytically and experimentally. This is one of the important practical problems of autonomous fluid-structure systems with many interesting motions. Both fluid-damping and fluid-stiffness controlled instabilities were investigated. Depending on the system parameter, the dynamic response of the tubes includes periodic, quasiperiodic, and chaotic motions. The analytical model is based on the unsteady flow theory, which can predict the nonlinear dynamics of tube arrays in cross flow. For fluid-damping controlled instability, analytical results and experimental data agree reasonably well. This study was applied to heat exchangers.
