Effect of subgrid-scale anisotropy on wall-modeled large-eddy simulation of turbulent flow with smooth-body separation
Di Zhou, H. Jane Bae
We examine the role of anisotropic subgrid-scale (SGS) stress in wall-modeled large-eddy simulation (WMLES) of flow over a spanwise-uniform Gaussian-shaped bump, with emphasis on p…

Consistency requirement of data-driven subgrid-scale modeling in large-eddy simulation
Xinyi Huang, Sze Chai Leung, H. Jane Bae
Data-driven subgrid-scale (SGS) modeling in the large-eddy simulations (LES) suffers from the inconsistency between the \textit{a priori} tests and the a posteriori tests, which ma…
