Universal Thesis of Meanders
Takeo Nakagawa · SOCIALSCI JOURNAL · 2019
Proposed is a universal thesis of meanders: In any flow, the main thread of flow that is the locus of the fastest fluid particle in each the cross-section governs the whole meandering of flow. The main thread of flow plays the critical role in meanders of flow in such a way that if there is any disturbance the main thread of flow, as well as the flow itself, meander under the condition that the system of the rest subordinate surrounding fluid particles including boundaries is unstable. The balance between the disturbing force and the restoring force maintains the meandering of flow.
