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 …

I. Introduction he generation and proper distribution of streamwise vorticity in order to
enhance dispersion and molecular mixing of fuel and air in scramjet combustors is a key …

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 …

Air-breathing propulsion has the potential to decrease the cost per kilogram for access-to-
space, while increasing the flexibility of available low earth orbits. However, to meet the …

A combined experimental and computational study of two different swept-ramp injector
configurations was conducted in a scramjet combustor. The object of the study was to …

An experimental study of an aerodynamic ramp (aeroramp) injector was conducted at
Virginia Tech. The aeroramp consisted of an array of two rows with two columns of flush-wall …

For future airbreathing propulsion systems with flight Mach numbers above approximately
M= 6 scramjets should be used instead of ramjets due to a higher specific impulse, lower …

I. Introduction he quantitative measurement and characterization of the mixing efficiency of
fuel injected into a supersonic freestream is essential for facilitating the development of key …
