A geometry-based dynamically constrained sub-grid model for large-eddy simulation

A new sub-grid scale (SGS) model for large-eddy simulation (LES), referred to as the cascade-admissible geometric SGS (CAGS) model, is proposed based on an invariant representation of the local velocity gradient. The model interprets SGS activity through the geometric structure of the resolved deformation field using i...
