Vortex-induced vibrations (VIV) are a critical aerodynamic phenomenon affecting the dynamic performance and structural integrity of long-span bridges. These oscillations arise when alternating ...
When fluid flows past a blunt object at high speeds, it creates unstable swirling patterns called Kármán vortices. These ...
Fluid flow across a flexible or elastically mounted structure causes vibrations due to vortex shedding and other similar instabilities, like galloping. The flow-induced vibrations (FIV) are ...
