Numerical modeling of the plasma processes taking into account the products of transfer processes from aqueous solution of sodium chloride being used as a cathode

Abstract

The modeling of the formation processes and further transformations of active particles in atmospheric pressure discharge plasma with a sodium chloride solution used as a cathode is performed. Experimental data on the composition of the gas phase and the physical parameters of plasma were used in the numerical simulation. It is determined that electron collisions with water molecules leads to a change in the form of the electron energy distribution function. As a result, the rates of the processes occurring under the action of the electron impact are altering. In addition, the transfer of water molecules to the gas phase leads to the appearance of new active particles, such as OH·, HO2·, H2O2. It has been established that the products of the transfer of solutes influence on the balance of charged particles thus the electric field strength are reduced. This results in changing of the rate constants of the processes occurring in the plasma.
