MEASUREMENT OF TEMPERATURES IN IONIZED GASES BY MEANS OF INFRARED RADIATION. I. INFRARED RADIATION AND TEMPERATURES OF PLASMAJETS. II. MEASUREMENT OF GAS TEMPERATURES IN THERMAL PULSES BY MONOCHROMATIC RADIATION PYROMETRY

Abstract

The application of monochromatic radiation pyrometry to measurement of plasma temperatures was investigated. Infrared emission and absorption spectra of nitrogen, argon, and helium plasmajets, with various admixtures, were measured, and plasma temperatures were determined from the infrared emission and absorption at selected wavelengths. Also, the infrared monochromatic radiation (IMRA) method of gas temperature measurement was applied to determination of gas temperature in thermal pulses. A detonation tube was constructed in which the infrared emission and absorption of a combustion wave could be measured through infrared-transparent windows. Infrared instrumentation was built to make measurements at the high speed required for observing thermal transients. (Author)
