BEHAVIOR OF AEROSOL PARTICLES IN A SUCTION BUNKER OF STANDARD DESIGN

摘要

A model is used for an ideal incompressible fluid with the discrete-vortex method to examine the behavior of a multifraction set of dust particles formed on handling loose iron-ore materials in nonstationary vortex gas flows in a suction bunker with single walls of standard design. Four models are considered for the velocity pattern within the bunker. In all cases, it is found that the large fractions of dust are deposited on the floor of the bunker.
