This article covers the 9 most common types of fluid-structure interactions, including VIV, FEI, flutter, sloshing, and WSI.
7 Most Common Types of Fluid-Structure Interactions
Fluid-structure interaction (FSI) refers to the study of the interaction between a fluid and a structure. It is a complex field of study that is crucial in many engineering applications, including aerospace, civil, and mechanical engineering. FSI is a critical phenomenon that affects the performance, stability, and safety of many engineering systems. Here are seven of the most common types of fluid-structure interactions:
1. Vortex-induced vibration (VIV)
Vortex-induced vibration (VIV) is a type of FSI that occurs when a fluid flows around a structure, causing the structure to vibrate. VIV can be observed in many engineering systems, including offshore structures, bridges, and aircraft wings. The vibration caused by VIV can cause fatigue and failure of the structure if not controlled.
2. Fluid-elastic instability (FEI)
Fluid-elastic instability (FEI) is another type of FSI that occurs when a fluid flows around a structure, causing the structure to become unstable. FEI is commonly observed in heat exchangers, nuclear reactors, and steam generators. The instability caused by FEI can result in damage or failure of the structure.
3. Flutter
Flutter is a type of FSI that occurs when a fluid flows around a structure, causing the structure to oscillate in a self-excited manner. Flutter is commonly observed in aircraft wings, wind turbines, and bridges. The oscillation caused by flutter can result in damage or failure of the structure.
