Curvature-weighted spectra anticipate dissipation peaks in decaying three-dimensional turbulence
Satori Tsuzuki
We investigate the robustness of a curvature-weighted spectral precursor to dissipation in freely decaying three-dimensional incompressible turbulence. Building on our recent work…
Extreme-value statistics of curl-of-vorticity precursor peaks in perturbed Taylor-Green vortex turbulence
Satori Tsuzuki
Precursor peaks in the wavenumber maximizing the curl-of-vorticity spectrum have been observed to precede the dissipation peak in decaying turbulence. Becaus…
Distinct transverse-response signatures of retained-spin, eliminated-spin, and polynomial Burnett-type surrogate closures
Satori Tsuzuki
High-curvature observables in incompressible flows, including -weighted spectra, can arise from explicit internal rotation, elimination of a fast spin variable, or polynomial…
Spectrum of the Curl of Vorticity as a Precursor to Dissipation in 3D Taylor--Green Turbulence
Satori Tsuzuki
Predicting when a three-dimensional turbulent flow reaches its dissipation peak is essential for both theory and adaptive algorithms in simulations and experiments. Using direct nu…
