Abstract :
In this paper, a mathematical model was proposed to describe the behavior of OH and O radicals in the Dielectric Barrier Discharge (DBD) of NO/SO2/O2/H2O/N2 system with a cylindrical reactor, which energized by repetitive high voltage pulses at normal atmospheric pressure and room temperature. The generation and consumption of the radials were considered in the mathematical model by a single pulse or continuous pulses. Their concentrations were derived by considering the direct electron effect on the dissociation of gaseous molecules (O2, N2, H2O) and the subsequent excitation transfer reaction of excited oxygen atoms to produce OH radicals. The proposed equations were solved numerically by Rosenbrock method in MATLAB.
