A modeling simulation has been carried out for the electric potential distribution in zones EHD flow generated using pin-multi concentric ring electrodes and used as a comparator pin-single ring electrode. The pin needle was made from stainless steel with a tip diameter of 0.01 mm. The multi ring electrodes was constracted by dual concentric rings with a metal material connected to each other and each ring has a diameter of 24 mm and 16 mm in width and the ring thickness were 2 mm and 1 mm. Single ring electrode has a diameter, width and thickness respectively 24 mm, 2 mm and 1 mm. EHD was generated by using a DC high voltage of 10 kV. Pin functional as an active electrode of corona discharge while the concentric rings Multi/single ring electrodes acted as ions collector and passive electrodes. In this model uses Kaptsov's assumption for boundary conditions between the ionization zone and the zone of the EHD flow and the magnitude of potential use Peek's formula. Modeling results showed that the electrical potential at the center of dual concentric rings smaller than the electric potential at the center of a single ring.
