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 ...

Two degrees of freedom flow-induced vibration and heat transfer of an isothermal cylinder

International Journal of Heat and Mass Transfer, 2020
The effect of two-degree-of-freedom (2DOF) flow-induced vibration (FIV) on the characteristics of forced convective heat transfer from an isothermal circular cylinder is numerically simulated by commercial software-FLUENT in combination with the User ...

Two-degree-of-freedom flow-induced vibration of a rotating circular cylinder

Ocean Engineering, 2019
The flow-induced vibration (FIV) of a rotating circular cylinder in reduced velocity range of 3.0 ≤ U*≤14 is investigated numerically. The forced rotating cylinder can freely vibrate in flow and cross flow directions.

Flow-induced vibration of a circular cylinder with rigid splitter plate

Journal of Fluids and Structures, 2019
Flow-induced vibration (FIV) of a circular cylinder with an attached rigid splitter plate is studied. A stabilized finite element formulation is utilized to solve the incompressible flow equations in two-dimensions.

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.

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

Three-cylinder oscillator under flow: Flow induced vibration and energy harvesting

, 2020
This numerical study aims to examine the viability of energy harvesting by three rigidly coupled cylinders in an equilateral triangular pattern, as well as reveal the flow-induced vibration responses of such a system.

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

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 ...
