The exact boundary condition and nonuniform point distribution were used in the calculation. Numerical results including the electrical potential, electrical field, traveling DEP forces and particle behavior are presented. Although the LSFD scheme was originally proposed in solving incompressible viscous flow, it is further demonstrated in this paper that the method is also well suited for solving all kinds of DEP problems in which extremely high gradient of electric field exists in the computational domain, e.g. edges of the electrodes. The LSFD method enables the computational ease of free point/mesh distribution in these areas and hence save the computational efforts. © World Scientific Publishing Company.||Source Title:||Modern Physics Letters B||URI:||http://scholarbank.nus.edu.sg/handle/10635/73703||ISSN:||02179849||DOI:||10.1142/S0217984905010359|
