DIAGNOSTICS OF NON-REACTING AND REACTING SUPERSONIC FLOWS IN A SCRAMJET MODEL COMBUSTOR USING NON-INTRUSIVE SPECTROSCOPIC METHODS
ABSTRACT
The research on SCRAMJET combustors motivated the work on new non-intrusive measurement approaches to study the flowfield inside a combustor during operation. This was made possible by the development of new powerful laser systems and cameras with high spatial and time resolution. In this paper, we report an investigation of the swept ramp injector concept in a nonreacting as well as a reacting flowfield of a hydrogen-fueled supersonic model combustion chamber. To visualize the structure of the flame and the distribution of OH and O2, as well as to determine the averaged temperature and pressure field within the combustor, we used natural fluorescence (without laser excitation) and different laser-induced predissociative fluorescence (LIPF) excitation/detection schemes.
