Description
Summary:Nonunique ozone concentrations at the output of an ozone generator under identical external conditions of barrier discharge activation of N 2 /O 2 mixtures but with different prehistories of operating practice and employed gas mixtures are investigated theoretically. An analytical approach is developed to determine the ozone yield with regard for its heterogeneous loss. Plasma-chemical and electron kinetics in the N 2 /O 2 -mixtures are calculated numerically. The results of numerical calculations are compared to experimental data obtained by the authors. It is noted that the heterogeneous loss of ozone is the probable reason for the observed variety of behavior of О 3 concentrations, depending on prehistory of ozone generator operation, along with the N 2 and O 2 gas flow rates and the specific active power.
