This study presents the mathematical model of a dielectrophoretic microfluidic flow separator with interdigitated transducer electrodes. The model considers the forces associated with inertia, drag, gravity, buoyancy, and dielectrophoresis. The device's efficacy in separating a binary mixture, of silica and polystyrene microparticles, into homogeneous silica and polystyrene samples is demonstrated. The model analyzes the influence of volumetric flowrate and applied electric potential on separation efficiency and purity.
