- •
The HIT flows are calculated by the D-IP method from the kinetic level.
- •
The effect of differential diffusion is closely related to the tetrad initial size.
- •
While it weakly depends on Reλ and has a long memory beyond the dissipation scale.
- •
Molecular diffusion makes the shape distortion close to the inertial range scaling.
