Abstract

The approximate deconvolution model (ADM) for largeeddy simulation (LES) is formulated for a 2nd-order finite-volume scheme. With ADM, an approximation of the unfiltered solution is obtained by repeated filtering, and given a good approximation of the unfiltered solution, the nonlinear terms of the Navier-Stokes equations are computed directly. The effect of scales not represented on the numerical grid is modeled by a relaxation regularization involving a secondary filter operation³. A turbulent channel flow at a Mach number of M=1.5 and a Reynolds number based on bulk quantities of Re=3000 is selected for validation of the ADM implementation in a finite-volume code. A direct numerical simulation (DNS) of this configuration has been computed by Coleman et al.¹⁸. Overall, our LES results show good agreement with our filtered DNS data. For this rather simple configuration and the low-order spatial discretization, differences between ADM and a no-model computation are found to be small.
