Fluidelastic instability tests on an array of tubes preferentially flexible in the flow direction
TL;DR: In this article, the stability behavior of a rotated triangular array is investigated in detail, with a fully flexible array, a single flexible tube, and a finite number of flexible tubes at several locations within the otherwise rigid array.

The effects of support geometry on the turbulence response of loosely supported heat exchanger tubes
TL;DR: In this article, the effects of support clearance and flow orientation for various support geometries and lattice-bar support offset are investigated for a loosely supported heat exchanger tube excited by turbulence.
Journal ArticleDOI
Robust control of chaotic vibrations for impacting heat exchanger tubes in crossflow
TL;DR: In this paper, a robust feedback controller is proposed to suppress flutter-type chaotic vibrations in baffled heat exchanger tubes, which are caused by the fluid dynamic forces on the tube which behave as a negative damping element.

The Post-Hopf-Bifurcation Response of a Loosely Supported Cylinder in an Array Subjected to Cross-Flow. Part II: Theoretical Model and Comparison with Experiments
TL;DR: In this paper, a nonlinear quasi-steady model for the analysis of the dynamics of a loosely supported cylinder, which takes into account position-dependent nonlinear fluid forces as well as nonuniform flow, is formulated.
Journal ArticleDOI
Intermittency transition to chaos in the response of a loosely supported cylinder in an array in cross-flow
TL;DR: In this paper, the authors investigated the mechanisms leading to chaos for a cylinder within a loose circular support and found that at higher flow velocities, a subcritical bifurcation of a period-1 orbit leads to type I intermittency.

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, the dynamic response of an inverted pendulum with motion limiting stops attached to a sinusoidally excited mass-spring system is considered. And the existence, stability, and bifurcations of these motions can be explicitly computed using a piecewise linear model.

Subharmonic and Chaotic Motions of Compliant Offshore Structures and Articulated Mooring Towers
TL;DR: In this paper, the authors used the resonance of articulated mooring towers, encountered in tank tests, to illustrate the general concepts of nonlinear dynamics of offshore structures and their sensitivity to starting conditions.
