説明
<jats:p>In this study, we investigate the applicability of the mean wall shear stress as a boundary condition for large eddy simulation of wall-bounded turbulent flow with coarse-grid resolution near the wall. We consider turbulent channel flow up to Reτ = O(108) and turbulent boundary layer flow up to Reθ = O(107). The mean wall shear stress is determined based on the log-law at every time step. It is shown that the mean wall shear stress boundary condition accurately predicts the logarithmic velocity profile and low-order turbulence statistics even with very coarse-grid spacing near the wall.</jats:p>
