Abstract

The article attempts to construct an equivalent circuit for measuring the electrokinetic potential transducer, the principle of operation of which is based on a shear flow. To obtain, an approach was used that is based on the phenomenological linear thermodynamic theory of irreversible processes using kinetic transport equations. Since the useful signal of the measuring transducer involves the use of a variable measuring signal, the equivalent circuit will allow optimizing the operation parameters of the measuring channel. A feature of the considered measuring transducer is the combination of two non-electrical phenomena as the simultaneous movement of a liquid under the action of external pressure and rotation of the transducer elements. By relating the flows of mass and electric charge, we obtain expressions for constructing and analyzing the equivalent circuits of the developed electrokinetic converter.

An analysis was carried out for various modes of operation of the electrokinetic converter and the main ratios were obtained. In particular, the potential mode, the current mode, the mode of maximum efficiency and the mode of maximum output electric power are singled out separately. On the basis of theoretical prerequisites, a number of options for constructing equivalent circuits and calculation formulas for calculating their parameters are proposed. The results of the work provide for further refinement to take into account not only static, but also dynamic parameters of the equivalent circuit.
