| Abstract: | In this paper, the results of plane turbulent wake given by Zhou Peiyuan are considered as the first order approximation and put, into the equations of turbulent fluctuation. The equations are solved numerically within the range of micro-scale by means of spectrum method. The double, triple and quadruple fluctuating velocity correlations are obtobred by computation. They are in a good agreement with experimental results. |

| Keywords: | higher order correlation self-preservation successive substitution plane turbulent wake numerical computation |
