Clean numerical simulation of three-dimensional turbulent Kolmogorov flow

Published in Physics of Fluids, 2025

This paper focuses on the Clean Numerical Simulation (CNS) of a three-dimensional (3D) turbulent Kolmogorov flow. By comparing the CNS benchmark solution with Direct Numerical Simulation (DNS) result, the study reveals that the spatial-temporal trajectories given by DNS are often polluted by numerical noise rather quickly, which significantly influences the spatial symmetry and energy cascade of the flow field.
