✦ Synopsis

Recent experiments have shown that an AC electric field induces steady fluid flow at or near the surfaces of microelectrodes. The flow velocity is a function of frequency and applied voltage and deriving a full theoretical model has proved difficult. Recently in this journal, M. Scott, K. V. I. S. Kaler, and R. Paul (J. Colloid Interface Sci. 238, 449 (2001)) presented a new theoretical model that not only is less comprehensive than previous ones but also is in direct contradiction to established fundamental principles of electrokinetics.
