Numerical Study of Flow-Induced Vibrations of Multiple Flexibly-Mounted Cylinders in Triangular Array

Abstract

The paper presents the numerical study of vibrating multiple flexibly-mounted cylinders in a triangular rod bundle. Behavioural trends of six different clusters of oscillating rods have been analysed. The influence of neighbour cylinders on the central cylinder oscillation characteristics is analysed. Finite volume solver of open source computational fluid dynamics is used to calculate the fluid flow in the channel with the cylinder array. Built-in six degree-of-freedoms solver is utilised to simulate cylinder movement. Oscillating cylinders have two degrees-of-freedom. The obtained results are compared with numerical results available in the literature.

Coupling vibration analysis of heat exchanger tube bundles under different stiffness conditions

“…The fluid-induced vibration of the tube bundles involves the interaction between the fluid and solid domain, which is challenging to calculate numerically 25 . Based on the computational fluid dynamics method, this paper establishes a simplified fluid-tube coupling vibration calculation model using the dynamic mesh method.…”
