Title: Recent research on fuel injection and mixing and piloted-ignition for scramjet combustors
Abstract: Current results obtained in a continuing NASA research program designed to establish basic design principles for the scramjet engine are presented on fuel injection and mixing and on piloted-ignition in supersonic flow. Specific data and correlation methods are included on penetration, lateral spreading, and mass concentration decay for the normal injection of hydrogen from the wall. Overlapping mixing patterns are concluded to be required for uniform mixtures. For parallel injection in the stream, an improved eddy-viscosity model is evaluated by comparing with data. NASA and other data obtained in turbulent flame studies with piloted-ignition in uniform supersonic mixtures indicate propagation velocities on the order of two decades lower than combustor through-flow velocities.
