Experimental Investigation of Annular Cascade Performance.
Abstract
The purpose of this experiment was to verify the analysis of radial equilibrium for compressible flow through a stationary cascade, where radial equilibrium is defined as uniform axial mass flow. Experimental determination of the effect of compressibility on analytical predictions of flow angle was of primary importance. Previous analytical work is summarized and those results shown. A specially designed annular flow test apparatus was constructed for this work and its features are described in detail. Finally, the results of detailed flow field surveys using three different blade angle settings are summarized and compared with both the free vortex and the Engelman analysis. In order to aid visualization of the real flow field as measured, various computerized graphical presentations of the data are shown. In addition, these survey results are compared with analytical predictions from a two-dimensional computer program developed by the General Electric Company and a three-dimensional computer program developed by AiResearch Manufacturing Company of Arizona.
