Analysis for fluid-elastic instability of tube arrays in cross-flow

To date, no study has been conducted on analytical methods to solve the fluid dynamics governing equations system for the fluid-elastic vibration of tube arrays in a straightforward manner. In this paper, a semi-analytical method for this vibration problem is investigated by considering the system a...
