順圧力勾配下の乱流境界層におけるエントレインメント機構の解明

抄録

Turbulent/non-turbulent intermittent structure in the outer layer was investigated experimentally with the aid of momentum transport equation with 5 component decomposition of the fluctuating velocity components. Considerations can be connected to significantly reduce of wake strength in the law of the wake and turbulent diffusion of the kinematic energy equation. Evaluate of some leading components of the momentum transport around turbulent/non-turbulent interface provide motions contributing to entrainment and pressure gradient effect.
