Flow Induced Vibration

1984
A central goal in the thermal design of tubular heat exchangers is to utilize the available shellside pressure loss to maximize the shellside film coefficient. The most effective means of accomplishing this objective is to arrange the shellside fluid to flow across the tube bank. Single segmental baffles (Fig.

Active Control Of Flow-induced Vibration

Journal of Sound and Vibration, 1993
Abstract The active control of flow-induced oscillations, specifically, vortex-induced oscillations of circular cylinders and galloping oscillations of circular cylinders and galloping oscillations of a square prism, are considered. In the case of vortex-induced oscillations, the vibrating cylinder is modeled as a single-degree-of-freedom (sdof ...

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

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 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 ...

ASPECTS OF FLOW-INDUCED VIBRATION

Journal of Fluids and Structures, 2001
Phenomena associated with flow-induced transverse oscillation of an elastically mounted body are considered. The use of a recently introduced parameter that combines the effect of mass and elasticity—effective elasticity—is exploited to demonstrate the predictive value of the new approach and to provide insights into solution branching, the maximum ...

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
