Physical significance of artificial numerical noise in direct numerical simulation of turbulence
Published in Journal of Fluid Mechanics, 2025
This paper investigates the often-overlooked physical significance of artificial numerical noise within Direct Numerical Simulation (DNS), proving mathematically and numerically how artificial disturbances mimic physical micro-level noises and disrupt the true solutions in chaotic fluid flows.
