Nozzle Geometry Effects on Strut Injection into a Supersonic Flow

摘要

Fuel injection from the base of a two-dimensional extended strut bounded aboveand below by Mach 1.92 freestreams was investigated. Without injection, a nominally two-wake flow exists behind the base of the strut. When fuel, simulated with helium, was injected parallel to the Mach 2 freestream, a highly three-dimensional complex flowfield results. The behavior of the flowfield generated by a: circular injection nozzle was compared to the results obtained with two
