Abstract

The separation of solid particles from the liquid or gas phase is commonly done using mechanical devices, the most important of which are cyclones. The simple structure and low production and maintenance costs have increased the use of cyclone separators in the electricity, petrochemical, cement, wood, etc. industries. This study assesses an electric field's impact on a square cyclone's performance. Reynolds stress method is used to model turbulent flow. One-way coupling is employed to track solid particles and the Eulerian-Lagrangian approach is used to model two-phase flow. A lithium-ion battery applies the electric field to the cyclone body, and the tangential velocity, axial velocity, and pressure drop are compared at different voltages. The results demonstrate that the applied voltage, in addition to increasing the tangential and axial velocities, which causes an increase in the centrifugal force in the cyclone, stabilizes the flow and brings purer air into the vortex. The increase in efficiency and decrease in pressure drop due to the application of the electric field indicates an improvement in the performance of the studied cyclone. The electric field makes the pressure drop caused by the fluid flow passage through the device much less than the device when the voltage is zero. As a result, the square cyclone can separate a wide range of particles with high efficiency and low pressure drop.
