Abstract

The contaminated substances in atmosphere are chemically reactive, and their reactions play main roles in the geneses of atmospheric pollutions. In this study, Large-Eddy Simulations (LES) with a two-dimensional enclosed region are carried out to investigate the influence of chemical reactions in turbulent flow fields. The bi-molecular reactions of Ozone with Limonene or Ozone with nitric monoxide, and wall deposition phenomena of these matters are modeled into the numerical analyses. The calculated results are consistent with experimental data. It is also revealed that the time fluctuation intensities of reactants concentration and their cross-correlations affect the mean reaction rates.
