Lagrangian evaluations of viscous models for velocity gradient dynamics in non-stationary turbulence

•A novel methodology to evaluate existing models (the linear Lagrangian diffusion model (LLDM) and the recent fluid deformation closure model (RFDM)) of the viscous processes incumbent in the evolution equation of velocity gradients employed.•Unlike previous evaluations, these evaluations are perfor...
