“…In the end, the time depends on the strength of the electric field, the polarization magnitude of the dielectric fluid, the electric potential distribution on the surface of the liquid and on the inclination angle of the electrodes with respect to the liquid surface, rather, from the value of its cosine [20]. It is found that the electrostatic transducer whose inclination angle of electrodes is in the range 40 ° -70 ° has the best performance [21].…”
