I. Introduction he combustion effectiveness of hydrogen fuel in an air-breathing scramjet
engine is known to be mixing-rate limited rather than reaction-rate limited1. This fact places …

Despite the recognized importance of streamwise vortices in the enhancement of fuel/air
mixing processes in scramjet combustors, the effects of their interactions on mixing and …

Work is underway at the NASA Langley Research Center to develop a hydrogen-fueled
supersonic combustion ramjet, or scramjet, that is capable of propelling a vehicle at …

Interest in supersonic ramjetkcramjet) engines has increased in recent years with the
establishment of research programs to develop horizontal take off and landing single stage …
