Analytical and Experimental Investigation of Stator Endwall Contouring in a Small Axial-Flow Turbine. 1 - Stator Performance
Abstract
An analytical and experimental investigation of three stator configurations was made to determine the effect of stator outer endwall contouring on stator performance. One of the stator configurations was a cylindrical stator design. One contoured stator configuration had an S-shaped outer endwall. The other contoured stator configuration had a conical-convergent outer endwall. The experimental investigation consisted of annular surveys of stator exit total pressure and flow angle for each stator configuration over a range of star pressure ratio. Radial variations in stator loss and aftermixed flow conditions were obtained. The experimental data were compared with the analytical results to assess the validity of the analysis. The experimental data were in good agreement with the analysis.
