Validation of a three-dimensional computational algorithm for viscous flow analysis has been conducted for two types of Francis turbine runner geometry, on low head and one high head, using experimental measurement. Assessment has been made for both qualitative features of flow behavior, as well as quantitative distribution of blade pressure and head loss. The influence of the grid size on the accuracy of the numerical solution is also discussed. Effort has been made to address some of the design issues, and to demonstrate that the present computational algorithm can make useful contributions to help improve the current design practices.
