Abstract:
In this paper, we present some results of OH molecular simultion spectra, to determine the gas temperature, for different distances of an atmospheric pressure plasma jet. The rotational temperature, of OH bands, is important for determining the gas temperature of flames and other combustion processes, as well as for a general exploration of the physical conditions in plasma. The intensity of OH bands is significant high. The rotational temperature determination is based on transition of OH free radical, which is present in the most plasma discharges. The resulted temperature, by simulation will be comparated with the experimental results. This report presents thus from the fundamenal data which are necessary for temperature measurements or other applications.
