The search for methods for taking into account a significant number of factors that affect the development of a positive corona discharge in technological processes determines the relevance of research in this area. The aim of the work is to determine for the streamer corona discharge in air at atmospheric pressure the influence of the geometric configuration of a multi-needle electrode system with a metal disk, as well as the air flow rate with its supply along the needles on the distribution of the electric field, the fulfillment of the avalanche-streamer transition condition, the ozone output and the energy consumption required for this. It is shown the existence of threshold values for the interelectrode voltage, needle lengths and distance between the needles, which limit the possibility of the appearance of streamers in the corona discharge. Based on the experimental results, in relation to energy consumption, it can be concluded that there are optimal values for the needle lengths and the distance between them. It was found that an increase in air flow in the electrode system during ozone production leads to a decrease in specific energy consumption and simultaneously to a decrease in ozone concentration. This relationship, depending on the purpose of the streamer corona discharge, must be taken into account in its practical application. References 7, figures 4, tables 2.
