A Study on Topological Vortex Ring Interactions Based on Möbius Loop and Hopf Link Concepts (3)
4. Superposition of Counter-rotating Vortex Rings and Knot Formation The situation is radically different when two vortex rings with opposite circulation directions (counter-rotating) interact: (1) Topological Description: Can be seen as the superposition of a positive Hopf link and a negative Hopf link. The total topological charge (net circulation) of the system is zero. (2) Dynamical...

A Study on Topological Vortex Ring Interactions Based on Möbius Loop and Hopf Link Concepts (4)
5. Discussion and Outlook The framework constructed in this study abstracts specific physical phenomena into topological operations: a. Co-rotating superposition ≈ Addition of topological charges, structure tends towards stability or higher-order linking. b. Counter-rotating superposition ≈ Subtraction of topological charges, structure tends towards generating singular knots or...
