System electrohydrodynamics equations applied to electroosmotic processes

A closed system of electrohydrodynamic (EHD) equations for such a specific subsection of electrohydrodynamics as electroosmotic phenomena is obtained. The EHD system does not contain the diffusion equation for the search for the field of ion concentrations. In the paper they are calculated more simply in the Debye-Hückel approximation. This makes it possible to simplify the calculation of electroosmotic potentials and ion charge densities. Correction of other equations of the EHD-system was carried out taking into account the features of electroosmotic processes. The presence of a heat conduction equation in the system makes it possible to calculate the temperature field in a liquid, which is extremely necessary for maintaining the necessary temperature regime when a new type of radiator is realized in practice.
