Geometric Intermittency in Turbulence
Ritwik Mukherjee, Siddhartha Mukherjee, I. V. Kolokolov +3
Equal-time scaling exponents in fully developed turbulence typically exhibit non anomalous scaling in the inverse cascade of two-dimensional (2D) turbulence and anomalous scaling i…

Topological flow data analysis for transient flow patterns: a graph-based approach
Takashi Sakajo, Takeshi Matsumoto, Shizuo Kaji +2
We introduce a method of time series analysis for two-dimensional transient flow patterns based on Topological Flow Data Analysis (TFDA), a new approach to topological data analysi…

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…
