MEASUREMENT OF TEMPERATURE IN )#US DETONATIONS BY MONOCHROMATIC RADIATION PYROMETRY.

Abstract

The infrared monochromatic radiation (IMRA) method of gas temperature measurement was applied to determination of temperature in gaseous deto nations. A detonation tube facility was con structed in which the infrared spectral emittance and absorptance of a detonation wave could be measured through infrared-transparent windows. A high speed infrared monochromatic pyrometer, which has time resolution of better than 10 microsec onds, was used to make the temperature measure ments. For hydrogen-oxygen, propane-oxygen, and propane-oxygen-nitrogen mixtures, initially at one atmosphere pressure, the measured tempera tures agreed with theoretical values calculated on the basis of the Chapman-Jouget theory. The measured temperature was independent of spectral wavelength, demonstrating that thermal equilib rium was attained. (Author)
