Material deformation tensor in time-reversal symmetry breaking turbulence

Material deformation tensor in time-reversal symmetry breaking turbulence

The properties of material deformation tensor in time irreversible turbulence are determined. It is shown that time irreversibility in the Lagrangian framework is connected with energy flux of the turbulence.
