Abstract:

Numerical predictions of turbulent vortex flow in cyclone chambers are made with the aid of a two-equation model of turbulence which entails the solution of elliptic differential equations of the transport of turbulence energy and its dissipation rate. The non-homogeneous and anisotropic nature of turbulence is accounted for by employing a two-viscosity concept. Reasonable agreement is obtained between the calculated axial and tangential velocity profiles and the experimental data available in the literature.
