Abstract

The paper focuses on the development of an approximate deconvolution method (ADM) for large eddy simulation (LES) of turbulent reactive flow. We derive the effective filter as a product of the LES filter and the filter induced by spatial discretization performed using high-order compact difference schemes. We analyze the accuracy of the ADM depending on the effective filter definition in the case of modelling unsteady combustion phenomena (ignition and flame extinction) in a forced homogeneous isotropic turbulent field
