Abstract The active pulsing air separation is a new method for dry material classification, which is specially suitable for electronic scraps disposal and re-utilization. By studying the difference of drag coefficients of the particles moving through areas of varying Reynolds numbers, and considering the extra-mass forces acting on the particles in the active pulsing air field, dynamic models of particles in the pulsing air flow were developed, both in Stokes and Newtonian fluids. A numerical simulation was completed for the particles with different densities and/or diameters, but similar aerodynamic characteristics. The moving properties in the turbulent flow were studied, and the parameters of the models were optimized. The results show that the simulation results were identical with the measured results by artificial tracing particle in the laboratory. This method provides a new and efficient approach for resource re-utilization.
