Abstract—Modern design method can not only make up the shortcomings of the traditional design method, but also be compared on the computer, it can save a lot of trial and testing costs in new product development and play an important role in optimizing the existing products. This paper studies the modern design methods of hydraulic machinery by the use of computational fluid dynamics (CFD) combined with CAD, which improves the blade shape according the analysis results to achieve the best design. Firstly the CFD calculation of the flow is applied to the runner blade of francis, then we analysis and evaluate the flow character and cavitation characteristics of the flow field in the inlet of the blade under the large flow, finally we carry on improving the inlet flow and cavitation characteristics by rebuilding the blade shape, the simuliaton results show the modified runner has better resistance to cavitation

Index Terms—Francis turbines, computational fluid dynamics, CAD, modern design method
