Predicted and measured barium titanate particle position in (a) 2-propanol and (b) methanol in a domain having 60 μm wide electrode and 40 μm gap between electrodes. Here, the lateral shift is the distance between the electrode edge and the particle center. Applied potential is 7.5 V. The numerically predicted slip velocity at the tip (edge) of the electrode is presented with the dotted line as a function of frequency. The vertical (y) equilibrium positions of particle are also calculated from the force balance in the y-direction by considering particle's weight, dielectrophoretic force, and viscous drag from the AC electroosmotic flow, but they are not presented here due to lack of reliable experimental data in the vertical direction.
