Reduction of dust extraction from an aspiration shelter due to mechanical shielding

The dust dynamics in an aspiration shelter equipped with various thin mechanical screens is considered. To calculate the trajectories of dust particles, the differential equation of their motion was used, the velocity field of the air flow was calculated by the method of boundary integral equations. The influence of different mechanical screens on the maximum diameter of dust particles is determined. It is shown that when using curved mechanical screens it is possible to significantly reduce dust extraction in the suction network.
