Abstract

Abstract

To investigate the evolution of single-phase flow-induced vibration response in helical coiled tubes and elucidate the vibration mechanisms in both in-plane and out-of-plane directions, this study conducts experiments of single-phase flow-induced vibration in helical coiled tubes using laser Doppler measurement technology. By performing flow-induced vibration experiments at different inlet flow velocities and integrating modal analysis results, we examined the influence of flow velocity on coil vibration response and explored the characteristics of vibration response in both in-plane and out-of-plane directions. The experimental results indicate that the in-plane vibration characteristics of the helical coil are influenced by the static force and mass, while the out-of-plane vibration characteristics are related to the system mass. The RMS of out-of-plane vibration displacement decreases with the increase of height. By analyzing the flow state within the tube, the study reveals the impact mechanism of secondary flow on the vibration response of the helical coil. These findings can provide reference for the study of flow-induced vibration in helical coils, and can provide support for the subsequent study of two-phase flow-induced vibration in the tube.
