Abstract
T he adaptive local deconvolution method (ALDM) (9) provides as ystematic framework for the implicit large-eddy simulation (ILES) of turbulent flows. Exploiting numerical truncation errors, the subgrid scale (SGS) model of ALDM is implicitly contained within the discretization. An explicit computation of model terms therefore becomes unnecessary. Subject of the present paper is a modification of the numerical algorithm that allows for reducing the amount of computational operations without a!ecting the quality of the results. Computational results for isotropic turbulence and plane channel flow show that the simplified adaptive local deconvolution (SALD) method performs similarly to the original method ALDM and at least as well as established explicit models.
