Vibration of a Tube with the Axial Loads and Fluid

Abstract:

Vibration of a tube with the fluid and axial load is focused. In a heat exchanger, the tubes are frequently affected by external force and fluid shock waves. Thus, tubes are often found to be vibrated. This vibration may alter the performance of the tubes and global heat exchanger. That a heat exchanger system is weakly coupled as the each tube is coupled to the adjacent one through the fluid is found. To understand the global system dynamics, the dynamics of a tube must be investigated first. In this work, the dynamic properties of a tube with the axial loads are investigated. The Galerkin method employed, the equation of a tube with the fluid effect can be to derive. Numerical results reveal that the axial load and fluid effects may affect the dynamic properties of a tube with fluid significantly.
