FLOW-INDUCED STRUCTURAL VIBRATIONS

This article investigates flow-induced vibrations (FIV) of structures, which represent one of the critical challenges in hydraulic, mechanical, and civil engineering systems. A comprehensive analysis of fluid–structure interaction was carried out using both experimental investigations and numerical simulations.

Modal Characteristics of a Wedge Throttle Valve System for Ultra-Deep Well Control

Shiyou jixie
Wedge throttle valve is a key component of choke manifold in modern drilling engineering. Its vibration characteristics are affected by the solid structure itself and also by the coupling of flow-field factors such as fluid pressure and flow rate.

On the steady streaming flow due to high-frequency vibration in nearly inviscid liquid bridges [PDF]

, 1998
The steady streaming flow due to vibration in capillary bridges is considered in the limiting case when both the capillary Reynolds number and the non-dimensional vibration frequency (based on the capillary time) are large.
