Characteristics of flow patterns and vortex core movement in a uniflow cyclone separator

摘要

The characteristics of flow patterns and vortex core movement were investigated in a uniflow cyclone separator. Numerical simulation was carried out with a Computational Fluid Dynamics (CFD) program of ANSYS Fluent. The objective of the current study is to investigate internal flow field and flow pattern in a Uniflow Cyclone Separator (UCS). Normal temperature (T_∞ = 20°C) and atmospheric pressure (P_∞ = 1 bar) were determined as an initial condition. Dry air of uniform velocity profile was injected into a separator inlet at u_(in) = 5.2 m/s and Re_(in) = 5551. Turbulent intensity was set to 5.4% in a separator inlet. Calculation results show that Reynolds Stress Model (RSM) was useful in modifying two-phased viscous turbulence flow.
