Intermittency-Driven Turbulence Cascade Memory Extends the Markov-Einstein Coherence Length Beyond the Canonical Estimate

Y. Sungtaek Ju

Using direct numerical simulation of forced isotropic turbulence at ${\text{Re}}_{\hat{I}}»\approx 1300$ and $\approx 433$, together with two independent Markov-by-construction null surrogat…
