Abstract
In this study, we propose a new hyper mixer fuel injection strut that can readily be incorporated into the basic NASA Langley scramjet engine. The proposed fuel-injection strut enhances mixing via the lobed-mixer concept employed in conventional turbofan engines. Our preliminary computational study indicates that this mixing-enhancement concept is very promising. Results for a scramjet combustor inlet Mach number of 3 indicate that a lobed-mixer fuel-injection strut generates significant secondary-flows for promoting rapid fuel/air mixing, while the loss in stream thrust is small.
