Abstract:

An experimental study is described whose objective is to assess the role of NO in the nonequilibrium vacuum ultraviolet VUV radiation from shock- heated air. The experiment utilizes a splitter-plate shock tube technique wherein the VUV radiation behind a reflected shock is used as a light source to measure the absorption by gases processed only by the incident shock wave. In addition, nonequilibrium radiation profiles behind strong incident shock waves are also measured to aid in the identification of the relevant excitation processes. The report describes the apparatus and presents the results of calculations needed to establish testing parameters.
