| Popis: | Suction hoods are used on a wide-spread basis in ventilation equipment in order to capture harmful substances released by process equipment. The efficiency of such devices is dependent not only on the relative position of the source of contamination and that of the suction hood but also on suction uniformity. Where the location of the source and that of the suction hood is misaligned, the need arises to put in place an uneven velocity field in the suction hood. This papers explores the flow of hazardous substances from the “source” to the “sink” located at an angle of 180 degrees relative to each other. Collection efficiency was determined numerically by means of the Fluent software as well as experimentally. A screen was mounted inside to ensure uneven suction. The study yielded flow current lines and constant temperature lines. It also helped to define maximum suction intensity. The findings may be used for designing ventilation systems intended for industrial buildings. |
