Aerodynamic analysis of the multichannel air cleaning equipment with curvilinear channels

Abstract

The aim of experimental tests is to determine aerodynamic characteristics in an improved multichannel cyclone with a spiral shell. This device was developed in order to improve the separation of ultra-fine solid particles from a polluted air (gas) flow. The purification device was designed at the Department of Environmental Protection (DEP) of Vilnius Gediminas Technical University (VGTU). Since the quality of air (gas) flow cleaning process is largely dependent on aerodynamic characteristics (air flow velocity and device’s resistance), air (gas) flow velocity in a multichannel cyclone with a spiral shell and the overall resistance of the cyclone device depending on the number of channels and the positioning of curvilinear semi-rings were determined during experimental tests.
