Abstract

Modeling of aerodynamics in an air-centrifugal classifier, the separation zone of which consists of rotating profiled disc elements, between which a turbulent swirling flow is observed in the direction to the rotation axis, is carried out. The problem was solved numerically in the acquired orthogonal curvilinear coordinate system using the known turbulence model by Wilcox. The influence of mode parameters and the additional supply of the carrying medium on the aerodynamics in the separation zone of the centrifugal apparatus is shown. The reliability of the results is substantiated by test investigations and by a comparison with reference data.
