Progress in optical diagnostic development for the electro-thermal chemical program
Progress is reported on a development program whose goals are techniques suitable for the study of mixing and combustion during the electro-thermal chemical propulsion process. Specifically, it was desired to develop an optical technique capable of determining the location, extent and structure of a plasma-liquid interface at gun-like conditions, and to determine the location and intensity of combustion at that interface. Details of the adaptation of techniques developed for the study of liquid propellant combustion to ETC-like phenomena are described in this report. This includes how to obtain photographs capable of being analyzed to determine both the location and structure of the plasma-liquid interface and locations of regions undergoing chemical reactions, and details of digital image processing techniques useful in obtaining this information.
