Project
Vortex Ring
Simulation of vortex ring formation and propagation in fluid showing the coherent structure dynamics.
1 Challenge
Understanding vortex ring formation and axis-switching phenomena.
2 CFD Approach
Vortex ring simulations in a piston elliptical cylinder. When the piston stops, the vortex detaches and moves in the axial direction.
3 Results
After a small time interval, the minor axis X turns into major axis X and vice versa.
4 Engineering Conclusion
The simulation reveals the axis-switching behavior of elliptical vortex rings.
