Project
Fish Swimming (IBM)
Immersed Boundary Method simulation of fish swimming showing the body kinematics and vortex generation.
1 Challenge
Simulating fish swimming using the Immersed Boundary Method.
2 CFD Approach
Fish-like swimming motion was simulated with IBM. The lateral displacement of the fish backbone was prescribed as a function of time, mimicking body and caudal fin (BFC) locomotion.
3 Results
The simulation shows the body bending into a backward-traveling undulatory wave that extends to the caudal fin.
4 Engineering Conclusion
IBM effectively captures the vortex generation and thrust production in fish swimming.
