Abstract: To design a turbine stay vane as an integral part of the spiral case/stay vane/wicket gate waterpassage, both the vane geometry and the gate/vane position must be developed and analyzed. The computerized system presented here has been optimized to do this with minimal engineering time. Major components of this system are: Spiral case design analysis using the 'ANTHONY' flow prediction to determine stay vane inlet flow angles; Stay vane geometry generation and vane/gate tandem cascade setup for flow analysis; Multicasing of Douglas-Neuman/DEBRA flow analysis of the vane/gate positions to evaluate the hydraulic performance. The methods used to couple separate generation and flow analysis codes to form task oriented, efficient engineering tools are discussed.
