Project
Mackerel Swimming
High-fidelity simulation of mackerel swimming showing the body deformation and vortex generation during locomotion.
1 Challenge
Understanding the swimming mechanics of fish and vortex generation during locomotion.
2 CFD Approach
Viscous flow past an undulating mackerel for Re=3000 and Slip=0.6. Fine mesh (210x120x120) solution.
3 Results
Instantaneous streamlines and xy-vorticity contours show reverse Karman street in the wake.
4 Engineering Conclusion
The simulation captures the thrust generation mechanism in fish swimming.
