Accelerated flows are induced between parallel electrodes under an alternating electric field in insulating fluid dispersed dielectric particles. This accelerated flow has many advantages for manufacturing process and bio medical applications. In this study, the effects of the particle cluster length on the inducing mechanism of the accelerated flow are investigated using an experimental measurement and a numerical simulation. The micro particle imaging velocimetry and the micro particle tracking velocimetry were employed for the measurement of the velocity of the flow field and the particles motion. The Eulerian-Lagrangian method was employed to simulate the particles dynamics and the flow structures. As the result, it is clear that the length of the particle cluster near electrode surface has a critical role to induce the accelerated flow.
