Numerical analysis of steady incompressible turbulent flow in a cyclone separator.

摘要

Cyclone separators have been widely used in the chemical processes industry as a first or final stage of cleaning dust particles from industrial gases. These cyclones are simple to manufacture but complex to design. Traditionally, the designer of cyclone separators uses empirical expressions, based on experiments, of the overall pressure drop and grade-efficiency as a function of the geometrical parameters and operational conditions of the cyclone separator. In this study, a CFD code called FLUENT is used to develop a numerical analysis of steady, incompressible, turbulent flow in a cyclone separator. The combination of three-dimensional governing equations in cylindrical coordinates and a turbulent model is used to calculate the flow. The numerical results are compared with experimental data available in the literature.
