This paper is two dimensional numerical simulations of solid-liquid flow in straight micro-channel. It is shown that mixing effect of particle by applying AC electric field. Mixing is one of the important operations of μ-TAS. However, flow in micro-channel is laminar flow because of low Reynolds number. Therefore, mixing in micro-channel is difficult. Electric potential is applied at four channel wall electrode. Particle mixing is encouraged by interaction of forced convection and electro-osmotic flow. Mixing characteristics of particle is depends on frequency of AC electric field.
