Flow-Induced Vibration

Flow-induced vibration occurs when a fluid, like air or water, moves past a structure such as a pipe, bridge, or aircraft component. The flowing fluid exerts forces on the structure, causing it to oscillate or vibrate. These vibrations result from interactions between the fluid's pressure and the structure's movement, often influenced by the flow's speed and pattern. While sometimes harmless, excessive vibrations can lead to material fatigue or failure over time. Engineers study these effects to design structures that withstand such forces, ensuring safety and durability in various engineering applications.
