- •
Velocity and pressure near the turbulent/non-turbulent interface was measured.
- •
There was a thin interfacial layer between the turbulent/non-turbulent region.
- •
Layer thickness was 0.08 times the half-width of cross-streamwise profile of velocity.
- •
Rapidly changing of velocity, Reynolds stress, and pressure were found at the layer.
- •
Pressure diffusion has a role to transport turbulent energy to non-turbulent region.
