摘要：

The results of a systematic experimental study of the integral scale of turbulence generated by manipulators, such as grids and honeycombs, are presented. On the basis of the statistical processing of a large body of the experimental data (for 29 grids and 19 honeycombs) the dependence of the turbulence scale behind a manipulator on the relative downstream distance and the Reynolds number is established. A technique for reducing honeycomb flow conditions to those of flow past an equivalent grid has been developed. This makes it possible to present the experimental data for grids and honeycombs in the same functional form.
