The hydrodynamic aspects of functioning of a high-voltage infiltration nanogenerator employing the potential energy of a liquid entering a glass filter are discussed. This energy transforms into the electric energy due to the formation of a double electric layer owing to the triboeleсtrization effect during infiltration of the dielectric liquid through the porous structure. To solve the emerged problems, in the equations of a hydrodynamic flow along the infiltration path two local effective parameters were introduced: a mechanic density and dynamic viscosity. The working equations for the motion of the liquid were derived; their solutions for the velocity and the flow rate determining the electric characteristics of a nano-generator, the electric charge and potential as well as their physical relationships were obtained.
Keywords: nanogenerator, glass filter, infiltration, liquid velocity and flow rate, porous structure, triboelectrization, electric charge, electric potential, effective density and viscosity.
