โฆ Synopsis
Flow-induced vibration of coil springs due to an axial flow was investigated experimentally using a fundamental test apparatus. The effects of spring stiffness, gap between the spring and the inner rod and initial compression of the spring on the vibration of the coil spring were clarified, and a stability diagram is presented for this vibration. Furthermore, the effectiveness of the counter-measures developed for suppressing the flow-induced vibration are confirmed.

There are few published papers on the subject of flow-induced vibration caused by two-phase flow. Experimental data at the high pressure and temperature conditions which would correspond to practical operating conditions are extremely few. Furthermore, the mechanism of the two-phase flow-induced loa
Fluidelastic vibration of tube arrays caused by two-phase flow has been studied before. The critical flow velocity is usually estimated with a simple Connors-type criterion which is based on an average flow velocity, an average fluid mass density and damping in two-phase flow. However, there is no e
In order to improve the prediction of wear problems due to flow-induced vibration in PWR components, an inverse method for identifying a distributed random excitation acting on a dynamic system has been developed at EDF. This method, whose applications go far beyond the flow-induced vibration field,
