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

The necessary equations and boundary conditions are proposed for describing acoustic fields caused by electrokinetic phenomena: the presence of a double electric layer and an applied electric field that is the sum of a constant field and an electric field carrying acoustic information. Equations are considered for viscous incompressible and compressible fluid conditions, provided that the hydrodynamics of the stationary electroosmotic process and the acoustic process are calculated accordingly. From the expressions obtained, it can be seen that the processes occurring during acoustic electroosmosis have as much in common, and contain some differences from the processes of classical electroosmosis. The physical model developed in the work and the corresponding mathematical expressions obtained make it possible to calculate the acoustic characteristics of the radiator based on the presence of electrokinetic phenomena and to optimize its device. The obtained results can be used in scientific instrument making.
