Flow-induced vibrations of a circular cylinder due to turbulent internal flows

OSTI ID:6307925
Flow-induced vibration characteristics are experimentally investigated for a circular cylinder subjected to a turbulent internal flow. Analytical studies and modal analysis testing were also performed to investigate the free libration characteristics of the cylinder in air and in fluid. The obtained free vibration characteristics were used to aid interpretation of the flow-induced vibration test results. Test results show that the cylinder was excited by the turbulent axial flow and experienced a narrow-band random vibration consisting of many localized shell-modes. The RMS vibration amplitude was small. However, it monotonically increased with the flow rate.
