Proper orthogonal decomposition assisted subfilter-scale model of turbulence for large eddy simulation
Vilas Shinde
Abstract
A subfilter-scale model for large-eddy simulation is devised using proper orthogonal decomposition, assuming self-similarity among the finest resolved and subfilter scales. The model naturally manifests the forward and backward transfer of interscale energy as well as the correct near-wall scaling.
