Residual stress reconstruction for large-Eddy simulation

A modelling technique for Large-Eddy Simulation is presented, in which the residual-stress tensor is reconstructed by applying an optimal convolution operator to the resolved stresses. This convolution operator is defined as a Taylor-series expansion in which the coefficients are determined using a dynamic procedure. The method is evaluated for the 1D Burger’s equation as proof of concept. Promising results are obtained.
