چکیده
|
The time periodic electroosmotic flow of newtonian fluids through a semicircular microchannel is studied under the debye–hückel approximation. analytical series of solutions are found, and they consist of a time-dependent oscillating part and a time-dependent generating or transient part. some new physical phenomena are found. the electroosmotic flow driven by an alternating electric field is not periodic in time, but quasi-periodic. there is a phase shift between voltage and flow, which is only dependent on the frequency of external electric field.
