This paper is focused on the understanding of the hydrodynamic phenomena in a corona discharge plasma reactor, diagnosed by Laser Doppler Anemometry. In order to describe and quantify the gas flow structure inside the reactor, the electrical characterization of the system permits a complementary understanding of the gas motion. Then a recycling gas flow, due to elementary electrical breakdown, and a residence time obtained with the gas flow distribution, are calculated, which allows to describe the gas flow structure inside the reactor. The association of the electrical elementary phenomena and the gas flow macroscopic process allow the comprehension of the impulse behavior evolution during the treated gas residence time, in the area between the two electrodes.
