Title of the articleOn the calculations of circular-slotted uniform-suction exhaust hoods
Abstract.On the aviation industry are widely used technological-mechanical equipment, in terms of having a circular shape. To trap harmful Mark-tions from the specified equipment, used circular air intakes. The efficiency of such devices depends on the uniformity along the length of the suction air inlet at the lowest energy costs. Uniformity of suction at the lowest energy consumption, is offering to carry out the change of coefficient of discharge along the length of the suction slot (number of holes) by setting the internal screen. Experimental studies on an aerodynamic stand were conducted in the article. The results obtained during the experiments confirmed the correctness of made assumptions. The maximum deviation of the specific consumption does not exceed 8-10 %.
Keywords.air inlet ring, uniform absorption, internal screen, flow coefficient.
