摘要：In this paper, numerical flow investigation ofa propeller runner with 6 different blade runner geometries is carried out. The turbine efficiency prediction for this particular runner, performed for a wide range of operating conditions, is presented and compared to the result obtained with the average runner geometry. Also during the study, special attention is paid to the flow unsteadiness at runner outlet and in the draft tube cone at part load condition. The numerical results are validated against experimental data obtained from the AxialT project. The outcome of this comparison is important for future refurbishment projects with such particular differences in the runner blade geometry
