Notice of Retraction Simulation of flow through vibrating screens with moving body method

A CFD study of the flow through vibrating screens has been conducted with moving body method of PHOENICS. The flow fields around the static and vibrating screens were calculated with laminar and turbulence models respectively, and the pressure-drop coefficients for both states were obtained. It was found that the flow field became very complex and vortex and backflow were produced because of the motion of screens. The dynamic pressure-drop coefficient changes greatly due to the different velocity through screen induced by motion of screens. After obtaining pressure-drop coefficients of flows through dynamic screens, it becomes possible to simulate the whole flow field of a shaker for solid-liquid separation by using the porous media to replace the real screen.
