Investigation of two short annular diffuser configurations utilizing section and injection as a means of boundary-layer control
Year: 1955
Abstract: The performances of two annular diffuser designs applicable to turbojet afterburner installations were investigated to determine the effectiveness of injection and suction boundary-layer controls. The outer shell was cylindrical in each case. The basic center-body design was an abrupt dump type which produced an equivalent conical diffuser angle of approximately 1000. The addition of a conical center-body fairing to the basic design produced a second configuration corresponding to an equivalent conical diffuser angle of 320. Both designs had an area ratio of 1.9:1 and were tested with fully developed pipe flow at the inlet up to a Mach number of 0.45.
