Large Eddy Simulation consistently demonstrates superior accuracy in resolving detailed turbulent structures and complex flow features compared to traditional Reynolds-Averaged Navier-Stokes models, although it requires substantially higher computational resources.
The retrieved papers consistently demonstrate that Large Eddy Simulation (LES) and hybrid models incorporating LES outperform conventional Reynolds-Averaged Navier-Stokes (RANS) models in capturing detailed turbulence features, secondary flows, and localized dynamics across various applications (such as boundary layers, respiratory airflow, and pumps). None of the papers refute the accuracy advantage of LES; rather, they acknowledge RANS mainly for its computational efficiency despite its known limitations in resolving complex fluctuations.
