On the Electroacoustic Transformation Method Based on Electrokinetic Phenomena

Electrokinetic repeater of acoustic vibrations

“…The authors have earlier considered in [1,2] and other papers the acoustoelectric conversion based on such an electrokinetic phenomenon as electroosmosis. In [3] there was suggested an acoustoelectric conversion based on the electrokinetic phenomenon reverse to electroosmosis, i. e. flow potential that is sometimes referred to as current potential [4].…”

“…In [3] there was suggested an acoustoelectric conversion based on the electrokinetic phenomenon reverse to electroosmosis, i. e. flow potential that is sometimes referred to as current potential [4]. Analysis of studies [1][2][3] showed that in both the cases of direct and reverse conversion almost identical mathematical and physical models are applicable, which is caused by the conversion reversibility and, hence, by the reversibility of electrokinetic transducers.…”

“…The possibility of the retransmission mode was revealed in analyzing the motion equation as applied to the acoustoelectric conversion when constant DC electric field E 0 and external acoustic pressure field p a were simultaneously applied to the ends of the capillary filled with fluid. Here the process is analyzed by using the Navier-Stokes equation in the following form [1,2]:…”

“…Assuming that the process is potential, v ′ = ∇ ′ , v a = ∇ a as in [2], let us reduce the last equation to the scalar form:…”

“…In addition, relation (14) demonstrates the influence of other parameters of the process, for instance, inverse proportionality of the repeating effect to angular frequency ω. Other peculiar features of the equation (14) solution behavior are briefly described in [2].…”
