Abstract: The fluid-force coefficients for a row of cylinders and a square array are determined from available experimental data and critical flow velocities are calculated as a function of system ...

Abstract: A mathematical model is presented for a group of circular cylinders subject to cross-flow. It is found that there are two basic dynamic instability mechanisms: instability controlled by fluid ...

Abstract: The flow field around a pair of rigid circular cylinders is very complex and has been studied extensively. When either one or both cylinders vibrate, the flow field becomes significantly more ...

Abstract: Flow-induced vibration in heat exchanger tube banks is of great concern, particularly in high performance heat exchangers used in nuclear raactor systems. In this paper, the dynamic characteristics ...

Abstract: Two-phase flow exists in many shell-and-tube heat exchangers and power generation components. The flowing fluid is a source of energy that can induce small-amplitude subcritical oscillations and ...

Abstract: A general theory is presented to account for the out-of-plane motion of uniformly curved tubes containing flowing fluid. The systems are grouped as conservative and nonconservative according to ...

Abstract: Since the early 1970s, extensive studies of fluid-elastic instability of circular cylinders in cross-flow have been reported. A significant understanding of the phenomena involved now exists. ...

Abstract: Nonlinear dynamics of a heavy elastic suspended cable were investigated for application to a stack/wire system. Small oscillations of the cable at the support attached to the stack, the result of bending motion of the stack ...

Abstract: Chaotic vibrations associated with the fluidelastic instability of nonlinearly supported tubes in a crossflow is studied theoretically on the basis of the unsteady-flow theory and a bilinear ...

Abstract: The dynamic response of magnetically-levitated (maglev) ground transportation systems has important consequences for safety and ride quality, guideway design, and system costs. This article, which ...
