要約

On the basis of a two-point similarity analysis, the power-law variations for the different length-scales (e.g. the Taylor microscale, and the Kolmogorov scale) and the velocity scales (e.g. the rms, the Kolmogorov velocity) in the far-wake of a circular cylinder are derived. In particular, an exact relation for estimating the mean turbulent energy dissipation rate ε on the wake axis is obtained. All these relations are supported reasonably well by hot-wire data in the far-wake at a Reynolds number based on the free stream velocity and the cylinder diameter of 2000.
