Experimental Studies of Photoionization Processes in Air.

摘要

The experimental program described herein was designed to investigate vacuum ultraviolet radiation processes in air,with particular emphasis directed at the interaction of shock-induced nonequilibrium radiation with gaseous species. The program was divided into three main tasks which were: (1) To perform (NO) absorption measurements using a shock-tube splitter plate technique. (2) To investigate VUV excitation mechanisms using sidewall radiation overshoot measurements. (3) To perform endwall radiation measurements of the advancing shock front to verify previously developed excitation and radiative flux models. The results of this program are summarized.
