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.

The Flow-Induced Vibration of Cylinders in a Cross Flow

5th International Symposium on Fluid Structure Interaction, Aeroelasticity, and Flow Induced Vibration and Noise, 2002
Flow-induced vibrations occur in general heat exchangers and nuclear reactors. They cause the tube failures through fretting wear or fatigue. Fluid elastic instability may lead to vibration amplitudes large enough to cause tube-to-tube clashing and in such cases will lead to relatively rapid failures.

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 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 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 ...

Flow Induced Vibration In Subsea Production Systems

SPE Russian Oil and Gas Exploration and Production Technical Conference and Exhibition, 2012
Abstract In the design of subsea flow systems, integrity and reliability are of paramount importance. As the equipment must be designed to operate at a large variety of conditions, inherent to the many processes, evaluation of the integrity is complex.

Experiences with Flow-Induced VibrationS

Journal of the Hydraulics Division, 1965
Difficulties encountered in U. S. Bureau of Reclamation structures because of flow-induced vibrations show that similar problems can occur elsewhere and that measures can be taken to avoid or control them. Vibrations interfered with operation and caused structural damage in several radial gates in canals because of control shifting front the flexible ...

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
