A full stage simulation method is used to calculate the first numerically predicted hill chart of a high specific speed Francis turbine. The numerical method simulates rotating and non-rotating components and their mutual interactions within a single computation. An efficiency hill chart is determined numerically and compared to experimental results from a model test whereby good agreement is obtained.
