We conducted WMLES to examine the performance of a simple and widely used ODE-based equilibrium wall model in a spatially-developing 3D TBL inside a bent square duct (Schwarz and Bradshaw 1994) and 3D separated flows behind a skewed bump (Ching et al. 2018a,b; Ching and Eaton 2019). From the square duct simulation, the mean velocity profiles and crossflow angles in the outer region were predicted with high accuracy for all the considered mesh resolutions. Some disagreement was observed in the… 

Heat transfer in three-dimensional intersecting shock-wave/turbulent boundary-layer interactions with wall-modeled large-eddy simulations

The accurate prediction of aerothermal surface loading is of paramount importance for the design of high speed flight vehicles. In this work, we consider the numerical solution of hypersonic flow

Wall-modeled LES of a spatially-developing non-equilibrium turbulent boundary layer

Current subgrid-scale (SGS) stress models for large-eddy simulation (LES) are known to produce insufficient turbulent shear stress in the near-wall region of high Reynolds number wall turbulence when

TLDR
The performance of two wall models based on Reynolds-averaged Navier-Stokes is compared in large-eddy simulation of a high Reynolds number separating and reattaching flow over the NASA wall-mounted hump to improve flow prediction on a coarse grid.

An improved dynamic non-equilibrium wall-model for large eddy simulation

A non-equilibrium wall-model based on unsteady 3D Reynolds-averaged Navier-Stokes (RANS) equations has been implemented in an unstructured mesh environment. The method is similar to that of the

Integral wall model for large eddy simulations of wall-bounded turbulent flows

A new approach for wall modeling in Large-Eddy-Simulations (LES) is proposed and tested in various applications. To properly include near-wall physics while preserving the basic economy of

Dynamic slip wall model for large-eddy simulation

TLDR
A dynamic procedure for the slip coefficients is formulated, providing a dynamic slip wall model free of a priori specified coefficients that alleviates the well-known problem of the wall-stress under-estimation by current subgrid-scale (SGS) models.

TLDR
This work reviews recent investigations in wall-modeled LES, including the development of novel approximate boundary conditions and the application of wall models to complex flows (e.g., boundary-layer separation, shock/boundary-layer interactions, transition).

Log-layer mismatch and modeling of the fluctuating wall stress in wall-modeled large-eddy simulations.

TLDR
This work shows that both local temporal filtering and local wall-parallel filtering resolve log-layer mismatch without moving the LES-wall-model matching location away from the wall, and looks into the momentum balance in the near-wall region to provide an alternative explanation of how LLM occurs.

Large-eddy simulations of co-annular turbulent jet using a Voronoi-based mesh generation framework

Large eddy simulations are performed for a cold ideally-expanded dual-stream jet issued from cylindrical co-axial nozzles, with supersonic primary stream (Mach number M1 = 1.55) and subsonic

Wall-modeling in large eddy simulation: Length scales, grid resolution, and accuracy

This paper addresses one of the most persistent errors in wall-modeled large eddy simulation: the inevitable presence of numerical and subgrid modeling errors in the first few grid points off the

Turbulence structural changes for a three-dimensional turbulent boundary layer in a 30° bend

A three-dimensional turbulent boundary layer (3DTBL) was generated on the floor of a low-speed wind tunnel by the imposition of a cross-stream pressure gradient using a 30° bend in the horizontal
