Effects of several arrangements of rectangular vortex generators on the static-pressure rise through a short 2:1 diffuse
Year: 1951
Abstract: An investigation was made of a 2: l area-ratio diffuser of length equal to the inlet diameter with several arrangements of simple rectangular vortex generators over a speed range up to an inlet Mach number of 0.5. The investigation was for an inlet boundary layer 5 percent of the inlet diameter, a condition for which this diffuser had substantial separated areas with no vortex generators. The effects varied considerably between different vortex-generator arrangements. Some arrangements actually reduced the diffuser static-pressure rise. The effect of one of the better vortex-generator arrangements was to increase the diffuser effectiveness by 30 percent; this arrangement made it equal to that oaf diffuser of twice the length with no vortex generators.
