摘要：
Filtered subgrid-scale models are derived, which are less sensitive to the low-frequency modes than their original counterparts. They are obtained thanks to the definition of a high-pass discrete test filter. After presenting the theoretical derivation of these models, some a posteriori tests on the incompressible channel flow case are presented. (C) 2000 American Institute of Physics.
