On diffusive supersonic combustion (chemical kinetic effects in diffusive supersonic combustion)

, 1966
Simple analytical methods are presented for the analysis of chemical kinetic effects in supersonic combustion. Three different regions are shown to occur in supersonic diffusive combustion. The first region is close to the injector exit, where the flow may be considered frozen for the main reacting species and where the radical concentration is ...
