Key Points

This study aims to understand how finite Reynolds numbers affect structure functions in turbulent flow regions characterized by external intermittency.
High-resolution direct numerical simulations conducted for Reynolds numbers 10^4 and 10^5 based on nozzle width.
Analysis of conditional second-order and higher even-order longitudinal and transverse structure functions.
Conditional second-order structure functions exhibit self-similarity at small and intermediate scales.
Higher even-order structure functions progressively deviate from self-similarity, challenging Kolmogorov's universal equilibrium theory.
The unsteady term in the Kármán–Howarth equation becomes more significant as intermittency decreases, deviating from Kolmogorov's 4/5 law.
