چکیده

In present numerical simulation, using of RSM model assesses behavior of flow pattern in different gas cyclones and presumed that interaction of particle-particle is neglected ( one way coupling) that results indicate that installing angle curves at the end of tangential channel can improve collection efficiency than a conventional gas cyclone and pressure drop decreases nearby walls and also such curves can lead to stabilization of vortex end in the bottom of cone and increasing tangential velocity clos to walls. Increasing particle size and inlet velocity improve collection efficiency at all gas cyclone.

Cyclone separators or Aero-cyclones have been widely used in industrial applications [1], such as chemical processes and food drying. This device is popular among researchers and engineers due to its small size, low cost, and easy launching. In gas cyclones, the continuing phase ( AIR ) enters the inlet channel tangentially inside the cylindrical part. Due to the conical and cylindrical parts of the gas cyclone, it is a high swirl flow that causes turbulent gas flow. Numerical works have been carried out by many researchers who evaluate gas cyclone performance with geometrical changes. Gao et al.[2] have investigated the effect of central tubes in oil-gas cyclones. They reported that the effect of diameter is higher than high on gas flow. Raoufi et al.[3] studied the different shapes of vortex finder in a stairmand gas cyclone. y.
