Electrohydrodynamic transport of ozone in a corona radical shower non-thermal plasma reactor

In this paper results of the experimental investigation of ozone molecule transport along a corona discharge radical shower (CDRS) non-thermal plasma reactor are presented. The measured axial ozone concentration distributions along the CDRS reactor show that the ozone molecules produced in the discharge region were transported from their origin both in the upstream and downstream regions of the CDRS reactor, i.e. also against the main gas flow. The images of the flow structures in the CDRS reactor suggests that the electrohydrodynamic (EHD) flow is responsible for the ozone transport upstream. (author)
