Project
Inverted Cantilever in Wake of Cube
Simulation of an inverted cantilever oscillating in the wake of a cube. Shows complex fluid-structure interaction phenomena.
1 Challenge
Understanding the vibration of an inverted cantilever in the wake of a bluff body.
2 CFD Approach
An inverted cantilever mounted at the wake of a square cylinder was simulated. Initially, the cantilever vibrates with the frequency of vortex shedding from the cube.
3 Results
Contours of instantaneous out-of-plane vorticity show the cantilever changing to a lower frequency after a transient period.
4 Engineering Conclusion
The simulation reveals complex fluid-structure interaction in wake-induced vibration.
