description abstract	An investigation was conducted in a duct system having fully developed pipe flow to determine the effects of vortex generators on the performance of a diffuser having a whirling inlet flow. The annular diffuser had a constant 21-inch outer diameter, an over-all equivalent conical expansion angle of 15º, and a 1.9:1 area ratio. Tests of the diffuser having mean inlet whirl angles of 0º, 15.2º, and 20.6º were made. The vortex generators used in this investigation were rectangular, nonchambered airfoils, which were varied in chord, span, angle setting, number, and location.
