Notes:
A priori tests are performed to study the effect of the filter on the subgrid scale term in large-eddy simulation. Several filters, corresponding to finite-difference schemes of different order of accuracy, are applied to direct numerical simulation data. In particular, the effect of the filter on the importance of the Leonard term and on its correlation with the subgrid scale stress is investigated to evaluate, for different numerical schemes, the capabilities of subgrid scale models accounting for this term, such as scale-similarity or mixed models. © 1998 American Institute of Physics.
