Title of the articleDefinition of critical thickness of the uniform-suction panel
Abstract.The laws of the suction duct studied by many authors. For example, the effect of the ratio of the slit area free area duct is seen in the work of G.A. Maksimov. Based on experimental data, G.A. Maximov set for which values for air can be achieved even at a constant suction slit width. Works A.P. Davydov and M.A. Valiullin examined patterns of distribution costs in linear and circular air inlet through a number of individual holes or cracks. Suction panel are effective devices for trapping harmful emissions from large open surfaces. Their effectiveness depends largely on even predetermined distribution of air flow through the surface suction. The data of these experiments for uniformly-suction panels in the literature. For the experiments was specially designed and constructed uniformly-suction panel with variable thickness. The article provides some information on the study uniformly suction panels with holes of different diameters, calculated by the method of A.P. Davydov adapted for panels. Experimentally determined the critical thickness of uniformly-suction panel. Is also defined, and in what proportions УFотв/Fжс panel retains the functions of uniform suction. Experimental data allow us to calculate the overall characteristics of the panel in bands uniform suction with the required values of the living section of the suction Fжс. May also change the flow in the subject of the panel, not counting the diameters of the suction holes – simply by changing its thickness. The panel will operate as uniformly-suction.
Keywords.Uniform-suction panel, free area, the critical thickness of the panel, uniform suction.
