EMISSION OF OPTICAL RADIATION FROM HIGH PRESSURE GASES
Abstract
The observed spectral emittance of high temperature and density nitrogen was examine where the gas was ompressed isentropically to a temperature and pressure of 7200 K and 4500 kg/sq cm respectively. The analysis indicated that the radiation was composed of a near blackbody continuum and of nitrogen band emissions where the predominant bands were N2+(1-), N2(1+) and N2(2+). Examination of the ratio of the latter two bands then made possible the reconstruction of the temperature history of the gas in the vicinity of peak compression. It was determined also that in comparison to the temperature, the relatively high density ratio of 250 played a minor role in the emitted radiant intensity.
