This paper presents the numerical calculation of current–voltage ( I – V ) characteristics that were produced by a corona discharges plasma generator for a multipoint–plane configuration in air and its comparison with the experimental results. The total number of needles in this configuration is 8 × 4 = 32 with the distance between the point-to-plane electrodes (denoted as c ) as the variable. The I – V characteristic curve of the numerical calculation results matches that of the experimental results for cases with a large distance c ( c  = 3 and 4 cm), and it shows a large deviation for cases with a small distance c ( c  = 1 and 2 cm). Differences in the I – V characteristic curve between the experimental and numerical results are due to the symmetrical spread of the ion current from the point-to-plane electrodes, which is more pronounced for larger values of c .
