Preliminary investigation of the flow in an annular-diffuser-tailpipe combination with an abrupt area expansion and suction, injection, and vortex-generator flow controls
Year: 1954
Abstract: The performance of an annular-diffuser-tailpipe combination with an abrupt area expansion was investigated with and without flow controls in the form of suction, injection, and vortex generators. The diffuser bad a 21-inch-diameter straight outer wall, an area ratio of 1.9 to 1, and fully developed pipe flow at the inlet. Inlet Mach number was varied between 0.18 and 0.43 with a resulting maximum Reynolds number (based on inlet hydraulic diameter) of approximately 1.6 X 106. The ratio of the auxiliary air flow to the flow of the main stream was varied from 0 to approximately 4 percent.
