Combining Acoustic Induced Vibration and Flow Induced Vibration

Volume 3: Fluid-Structure Interaction; High Pressure Technology, 2022
Abstract During testing to support a program to improve acoustic induced vibration (AIV) assessments, it became clear that flow induced vibration (FIV) is excited at the same time; both mechanisms excite the shell flexural modes of the piping system, although their frequency characteristics are different but overlap.

Flow-Induced Vibrations in Bellows

Journal of Pressure Vessel Technology, 1989
Abstract Flow-induced vibrations have caused fatigue failures in a number of bellows units carrying cooling water flows. The bellows are made from Inconel 600 and have a nominal inside diameter of 20 mm. This paper presents the results of a project undertaken to study these vibrations and to develop a method for vibration alleviation ...

Multiphase Flow Induced Vibrations at High Pressure

Volume 4: Fluid-Structure Interaction, 2020
Abstract High pressure experiments were done to determine the pressure effect on multiphase induced forces. To that end, a series of water/gas, oil/gas and oil/water/gas vibrations measurements were performed at 10, 25, 45 and 80 bar at different liquid and gas rates in a horizontal, 2″, double Uloop test section installed at the Equinor

Flow-induced vibrations and the Landau equation

Journal of Fluids and Structures, 2013
Abstract The initial and general transient temporal behaviours of flow induced vibrations were studied particularly with regard to the extent with which self-excited, flow-induced vibrations can be described by the Landau equation. Three different cases are studied experimentally, using bodies with generic shape.

Flow induced vibration of thermowells

ISA Transactions, 1999
Abstract Traditional thermowell selection methods based on velocity rating tables are no longer a match for the demands of modern processes, and a new approach, involving dynamic analysis methods, is needed. Starting with the simplest possible thermowell, a uniform cantilever subjected to a combination of vortex shedding and drag forces, the dynamic ...

Optimal Control of Flow-Induced Vibration of Pipeline

Dynamics and Control, 2001
The authors derive the state equations, combining known equations for the dynamic bending of pipes with the effect of axial flow of the fluid. The transverse action of the fluid due to bending of the pipe is combined with the Euler-Bernoulli beam equation. The authors assign identical boundary conditions to all pipe supports. The dimensionless equation

Flow-Induced Vibration of Anisotropic Cylindrical Shells

5th International Symposium on Fluid Structure Interaction, Aeroelasticity, and Flow Induced Vibration and Noise, 2002
This paper deals with the vibration analysis of anisotropic laminated cylindrical shells conveying fluid. We focus on the axi-symmetric (n=0) and lateral (beam-like, n=1) vibration modes of the anisotropic cylindrical shells. Particularly important in this study is to obtain the natural frequencies of the fluid-structure coupled system and also to ...

Flow-Induced Structural Vibrations

Journal of the Engineering Mechanics Division, 1965
The problem of flow-induced structural vibration is characterized mainly by interdependence of structural deformation and fluid-dynamic loading. The analytical and physical nature of this problem, designated as fluidelasticity, is examined and exemplified, thereby developing a framework useful in unifying an otherwise heterogeneous group of vibration ...

Flow-induced Vibration and Instability of Carbon Nanotubes

2005 International Conference on MEMS,NANO and Smart Systems, 2006
This article deals with the effects of internal moving fluid on free vibration and structural instability of carbon nanotube (CNT) conveying fluid. CNT conveying fluid is an elastic hollow tube conveying fluid of mass density M and mean flow velocity V and it does not study how the wall-fluid interaction and the viscosity of fluid affect the mean flow ...
