Use of short flat vanes for producing efficient wide-angle two-dimensional subsonic diffusers
Year: 1958
Abstract: An investigation of the use of flat vanes in two-dimensional subsonic diffusers was made. Using optimum designs of vane installations, high pressure recoveries and steady flows were obtained for diffuser-wall divergence angles up to 420. Criteria for optimum configurations were developed which indicated that the vanes should be symmetrically arranged in the vicinity of the diffuser throat, that the vane-passage divergence angle should be approximately 7.0°, and that the vanes should have a certain predictable length dependent upon the diffuser geometry.
