摘要：
Experiments on deflagration in a vented vessel with a volume of 11 m(3) with internal obstacles in the form. of arrays of metal rods are described. Experimental and calculated curves of explosion pressure versus time are given. The effect of array parameters (rod diameter and cell size, the free cross-sectional area and the number of arrays, the spacing between arrays and their arrangement) on the explosion dynamics and turbulence factor for combustion inside the vessel are determined. Quantitative data on the turbulence factor for combustion in a vessel of large volume with obstacles in, the form of a set of arrays are obtained for the first time. In some cases, they far exceed the previously obtained values for the turbulence factor. It is shown that, according to theoretical predictions, the maximum explosion pressure correlates with the ratio of the turbulence factor to the discharge coefficient rather than, with the turbulence factor. A formula for the calculation of this ratio is proposed.
