OZONE PRODUCTION IN SUPERSONIC NOZZLES

Ozone production during the efflux of oxygen from a supersonic nozzle is studied theoretically and experimentally. The formation kinetics of atomic oxygen in an electrical discharge in the nozzle is analyzed. A n experiment is set up using an optimized nozzle with an electrical di scharge in its supersonic section. It is shown that the highest ozone content at the nozzle output is attained when the excess concentration of oxygen atoms is produced in the supersonic section of the nozzle.
