Wall-modeled large-eddy simulation for complex turbulent flows
Large-eddy simulation (LES) has proven to be a computationally tractable approach to
simulate unsteady turbulent flows. However, prohibitive resolution requirements induced by …

High–Reynolds number wall turbulence
We review wall-bounded turbulent flows, particularly high–Reynolds number, zero–pressure
gradient boundary layers, and fully developed pipe and channel flows. It is apparent that the …

Predictive large-eddy-simulation wall modeling via physics-informed neural networks
While data-based approaches were found to be useful for subgrid scale (SGS) modeling in
Reynolds-averaged Navier-Stokes (RANS) simulations, there have not been many attempts …

Predictive model for wall-bounded turbulent flow
The behavior of turbulent fluid motion, particularly in the thin chaotic fluid layers immediately
adjacent to solid boundaries, can be difficult to understand or predict. These layers account …

Machine learning building-block-flow wall model for large-eddy simulation
A wall model for large-eddy simulation (LES) is proposed by devising the flow as a
combination of building blocks. The core assumption of the model is that a finite set of simple …
