Vortex Induced Vibration of a Rotating Blade

Volume 2: Structures and Dynamics; Renewable Energy (Solar, Wind); Inlets and Exhausts; Emerging Technologies (Hybrid Electric Propulsion, UAV, ...); GT Operation and Maintenance; Materials and Manufacturing (Including Coatings, Composites, CMCs, Additive Manufacturing); Analytics and Digital Solutions for Gas Turbines/Rotating Machinery, 2017
The vortex-induced vibration (VIV) of a rotating blade is studied in this paper. Euler-Bernoulli beam equation and the nonlinear oscillator satisfying Van der Pol equation are used to model the rotating blade and vortex shedding, respectively. While the fluctuating lift due to vortex shedding acts on the blade and the blade is coupled with fluid ...

A Review of Vortex-Induced Vibrations

Earth and Space 2010, 2010
Vortex-induced vibration occurs when the vortex-shedding frequency for flow past a cylinder matches with the natural frequency of the cylinder. The result can be a transverse vibration or an in-line vibration of the cylinder, or a combination of the two.

A Revised Interpretation of Vortex-Induced Vibration

Offshore Technology Conference, 2017
Abstract Vortex-induced vibration (VIV) is a well-known phenomenon in the fields of physics and engineering. However, the description on vortex-shedding from a flexible or an elastically restrained cylinder (such as a deepwater riser or a floater) is somewhat primitive. When such a structure experiences flowing fluids, the pressure build-

Vortex‐Induced Vibrations of Flexible Bridges

Journal of Engineering Mechanics, 1990
One of the recurring aerodynamic concerns of both existing and projected new and flexible bridges, typically those of long span, is the possibility that the deck may be set into periodic oscillation by cross winds of relatively low velocity. This general phenomenon, regardless of the specific details of the local flow about the structures, has been ...

Vortex-Induced Vibrations of Structures

1981
Vortex-induced oscillations, often of concern when a bluff structure is exposed to fluid cross-flow, are considered herein using a semi-empirical modeling approach. Based on the fluid momentum theorem, the model involves a highly simplified abstraction of the complex flow field, and major assumptions concerning the nature of the coupling between the ...

VORTEX-INDUCED VIBRATION OF A FLEXIBLE CANTILEVER

Journal of Fluids and Structures, 2001
Abstract This study is concerned with the vortex-induced vibrations of a flexible cantilever in a fluid flow. Our cantilever comprises a leaf spring encased within a rubber flexible cylinder, restricting the vibrations of the body in a water channel flow to principally transverse motion.

VORTEX-INDUCED VIBRATION AND DAMPING OF THERMOWELLS

Journal of Fluids and Structures, 1998
Thermowells are installed in process piping to protect fluid temperature measuring instruments from the fluid flow. The thermowells are subject to vortex-induced vibrations by the process fluid. The resonant response is limited by damping. Measurements of thermowell vibration damping were made and used to establish criteria for acceptable design under ...

Vortex induced vibration of tall buildings

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract For a tall building of which aspect ratio is larger than 8, the resonant velocity of vortex induced vibration or the onset velocity of galloping can be within the design wind velocity. In this paper, the vortex induced vibration and the galloping of tall buildings with aspect ratio, H/√BD=10 with side ratios, D/B = 1 2 to 3 are ...
