Top: ζ_v(q) scaling exponents (50 distinct values; red dots) for the second regime of the CF4 velocity field. The exponents show clear deviations from monofractal behaviour (indicated by the straight line of slope 0.42). The dashed curve corresponds to the best UM fit (H = 0.42, α = 1.7, C₁ = 0.12). For q ≳ 2, a quasi-linear divergence appears, likely reflecting the increasing influence of a small number of high-gradient point pairs on the velocity statistics. Bottom: Empirical curve of qζ′(0)−ζ(q) as a function of q (blue dots) for the reconstructed CF4 velocity field, shown on a log–log plot, from which the UM parameters α and C₁ are directly inferred. We obtain α ≈ 1.7 and C₁ ≈ 0.12. For q ≳ 2, a weak linear divergence becomes visible, likely reflecting the increasing dominance of a small number of high-gradient point pairs in the velocity statistics.
