Methods of reducing the power requirements of ventilation systems. Part 4. Theoretical prerequisites for the creation of dust localizing devices with swirling air flows

A method of reducing dust entrainment from ventilation shelters through the use of swirling flows is proposed. The dynamics of dust aerosols in swirling ventilated currents is investigated by means of newly developed software and algorithmic support for the study of processes of dust entrainment in a ventilation network produced by devices that localize dust release. Keywords: ventilation shelter, transfer of granular materials, reduction of power requirements of ventilation systems
