Abstract

A cross-flow jet-type singlet oxygen generator has been developed, tested and analyzed in order to characterize the dependence of output performance on major input parameters. A thermal-balance model, which can predict O₂(¹Δ) yield, gas temperature, and gas residence time, is proposed, and the resultant theoretical results are compared to the experimental data. Combined with computational fluid dynamics-based gas residence-time analysis, the model provides good agreement with the measured value of the O₂(¹Δ) yield and the gas temperature. The surface chemistry model was applied to the measured Cl₂ utilization data, and was found to be inconsistent in the regime of high Cl₂ loading on the basic hydrogen peroxide jet, indicating that depletion of HO₂^- is taking place.
