Conclusion

The studies we conducted are aimed at improving the theoretical basis for design of

ventilated suction hoods used for bulk material transfer groups (i.e., the most typical

and common sources of dust emissions in dust-forming material reprocessing). The

basic ndings and resulting conclusions are as follows:

1. Aerodynamically, bulk material streams belong to a class of two- component

ows with a discrete carrying medium of solid particles falling at a growing

rate while also serving as a pseudo-continuous medium of induced air. The

accelerated motion of the carrying medium determines the asymptotic ...
