Abstract
We consider a method aimed at screening contaminants with the help of local exhaust ventilation whose important element is a local suction gun. We investigate the influence of the ratio of the geometric sizes of the suction gun and the circular hole and the ratio of the flow rates of intake and suction air on both the distance of suction entrapment and reduction of the dust flows in local closed-type suction guns. We also consider local suction guns in unbounded, semibounded, and bounded spaces.
