Abstract

In this paper we describe efforts to obtain canonical data sets to assist computational modelers in their development of models for the prediction of mixing and combustion in scramjet combustors operating in the ramjet-scramjet transition regime. The CARS technique is employed to acquire temporally and spatially resolved measurements of temperature and species mole-fraction at four planes, one upstream of an H2 fuel injector and three downstream. The technique is described and results are presented for cases with and without chemical reaction. The vibrational energy mode in the heated airstream of the combustor was observed to be frozen near facility heater conditions and significant nonuniformities in temperature were observed, attributed to non-uniformities of temperature exiting the heater. The data, which shows development of mixing and combustion downstream of injection, is already proving useful to the modelers.
