Aerodynamic aspects of polluted air aspiration in industrial rooms using cyclones

V. Kovalev, I. Klimenko

Abstract


In the proposed work a common method of effective gas cleaning from dust and other contaminations in industrial
premises by cyclone is considered. Similar methods are used in metallurgical, chemical, woodworking and other areas of industrial
production.
The analysis of existing methods and designs of cyclones is carried out, as well as the aerodynamic mechanism of vortex flows
formation in the separation chamber, of velocity and pressure fields distribution, and their development in time. The mathematical
model of the cyclone process based on the finite element method and the standard application package is proposed, which allows us
to construct a sufficiently reliable spatial picture of velocity and pressure fields distribution. The comparison of simulation results
with known experimental data indicates a qualitative reproduction of the cyclone process physical model.
