NACA-TN-3793
Exploratory investigation of the use of area suction to eliminate air-flow separation in diffusers having large expansion angles
Year: 1956
Abstract: Tests were made at a mean inlet Mach number of 0.2 with area suction applied to conical diffusers with expansion angles of 30 degrees and 50 degrees and exit to inlet area ratios of 2. Air-flow separation was eliminated with suction mass flows of 3 and 4 percent of the inlet mass flows for the 30 degrees and 50 degrees diffusers, respectively.
