ABSOLUTE INTENSITY MEASUREMENTS AND GAS EMIS SIVITIES AT ELEVATED TEMPERATURES AND PRESSURES.

Abstract

Similarity groups were derived for multicom ponent, reacting gas mixtures with radiative energy transport. Resulting relations were used to consider the feasibility of scaling for flow processes with radiative energy transport under highly simplified conditions. Oscillator strength and spectroscopic temperature deter minations on OH in a shock tube were carried out. The shock tube study of the 2.7 - 3.2 micron band of water vapor, was continued. The purpose of this study was simultaneous measurement of the absolute intensity of the band both in emission and in absorption at 1000 K. This objective was accomplished and emission measurements were made at 3000 K. Extensive data were collected on the absolute gf numbers of several lines of neutral and ionized chromium carbonyl. Data on the relaxation times for excitation and ioniza tion of chromium were also obtained in these experiments. Electronic temperatures for Cr I and Cr II behind reflected shock waves were measured.
