About one new method of electroacoustic transformation. A theory based on electrokinetic phenomena. Part I. The hydrodynamic aspect

As the basic physical model of a new type of electroacoustic transformation, it is proposed to use the theory of an electrokinetic phenomenon such as electroosmosis. The main details of the theory of transformation and associated hydrodynamic and electrical parameters are given. Hydrodynamics of steady electroosmotic motion of a liquid in a capillary is considered. Expressions are given for the flow velocities under the conditions of the presence of a total flow of two flows: the Poiseuille flow and the electroosmotic flow. A generalization of hydrodynamics of the electroosmotic flow to an arbitrary capillary-porous medium is also given. The acoustic aspects of the theory are supposed to be considered in the second part of this paper.
