Topological vortex identification for two-dimensional turbulent flows in doubly periodic domains

Mitsuaki Kimura, Takeshi Matsumoto, Takashi Sakajo +2

The dynamics and statistical properties of two-dimensional (2D) turbulence are often investigated through numerical simulations of incompressible, viscous fluids in doubly periodic…

Discrete representations of orbit structures of flows for topological data analysis

Takashi Sakajo, Tomoo Yokoyama

This paper shows that the topological structures of particle orbits generated by a generic class of vector fields on spherical surfaces, called {\it the flow of finite type}, are i…
