Gravity-driven separators are broadly used in various engineering applications to remove particulate matters from gaseous fluids meet legislation demands. This study represents a detailed numerical investigation of two-phase cyclone separator using the Eulerian–Lagrangian gas flow method. The turbulence is modelled Reynolds stress model (RSM). technique has successfully predicted typical trends...

In this paper the turbulent flow in a cyclonic separator is investigated with large-eddy simulation (LES) based on a cylindrical coordinate spectral-element-Fourier method (SEM) using the Smagorinsky subgrid-scale model in its standard and dynamic formulation. The results show slight model differences, but both have poor agreement with measurements. The cylindrical-coordinate system geometry us...

Cyclone separators are used in multi-phase flows for phase separation or classification. Pressure drop and efficiency essential parameters determining the performance of a cyclone separator, critical diameter is an important parameter related to efficiency. In this study, we investigate prediction ability various mathematical models; particular, approximately 400 experimental data available lit...

In the present work two turbulence modeling approaches, namely Large Eddy Simulation and Detached Eddy Simulation, are employed to predict the turbulent, swirling flow within an industrial cyclone separator running at Reynolds number 267,000. The results from three LES models, Smagorinsky, dynamic and Yakhot, and the SST-DES model of Strelets have been compared to experimental results for the a...
