A Study on Topological Vortex Ring Interactions Based on Möbius Loop and Hopf Link Concepts (1)Abstract This paper aims to explore the complex interactions of topological vortex rings in fluid mechanics and establish a novel topological framework for them. Vortex rings, as coherent structures carrying circulation and possessing stable topological structures, undergo interactions (such as collision, threading, and merging) that are inherently processes of topological transformation. We...0 发布评论计数 0 分享 46 查看 0 評論

A Study on Topological Vortex Ring Interactions Based on Möbius Loop and Hopf Link Concepts (2)2. Theoretical Foundation: Topological Invariants 2.1 Linking Number (Lk) For two simple, unknotted but mutually entwined closed curves (like an ideal Hopf link), the linking number Lk is a topological invariant representing the total number of times (with sign) one loop winds around the other. For two vortex rings, Lk quantitatively describes the topological strength of their mutual...0 发布评论计数 0 分享 47 查看 0 評論

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...0 发布评论计数 0 分享 44 查看 0 評論
