Abstract
The formation of ozone when partially dissociated oxygen flows out of a supersonic nozzle has been investigated experimentally and theoretically. The supersonic flow of a chemically reacting gas mixture containing excess O atoms is calculated in the one-dimensional approximation for a class of plane wedge-shaped nozzles. It is shown that for initial gas pressures ahead of the nozzle inlet of about 10 atm and a temperatureT0=1000 K in nozzles with a total vertex angle of 30°C and a throat dimensionh.=1 mm it is possible to obtain an ozone concentration of about 1%, which is comparable with ordinary ozonizers, while the output of the device is two to three orders greater. Experiments on a shock tube fitted with a nozzle to measure the absorption of UV radiation by oxygen recombining in the nozzle under highly nonoptimal conditions revealed the presence in the flow of ozone molecules formed as a result of O+O2 recombination.
